• Graphene is the lightest, strongest and most electrically conductive substance on Earth
• It has many uses in building materials, military equipment and smart technology
• The Graphene+ 2019 conference at Swinburne will discuss cost-effective and sustainable solutions to industry problems using graphene

Graphene is one of the most innovative materials to be developed and utilised this century.

Researchers at Swinburne have been heavily involved in its development, innovation and commercialisation. Later this month, the university will once again host the annual Graphene+ conference, bringing together industry leaders and academics to discuss the role graphene will play in the future of manufacturing and infrastructure.

What is graphene?

Graphene is both the lightest and strongest material known to man.  It is a single layer of carbon atoms arranged in a honeycomb-like structure and is the most electrically conductive substance on Earth.

It was discovered in 2004 by an unusual technique. Researchers from the University of Manchester in the UK used sticky tape to peel flakes from a lump of graphite, separating the layers until they were just one atom thick.

Graphene has proven highly versatile and has been used for building materials, military equipment, solar cells and smart devices.

Swinburne’s graphene ‘hub’

As part of the Graphene Supply Chain Cooperative Research Centre Projects (CRC-P), Swinburne is working with industry partner Imagine Intelligent Materials to develop graphene to meet strict quality assurances and to be used in large-scale manufacturing. It is also working to establish industry partnerships.

The material is also a key focus of the Next Generation Materials program, led by Professor Baohua Jia at Swinburne’s Manufacturing Future Research Institute (MFRI).

Director of the Manufacturing Future Research Institute, Professor Bronwyn Fox, says Swinburne researchers are working to establish standard knowledge and procedures for investors and suppliers of graphene.

“In the supply chain certification lab, we are developing the research to understand the relationship between the structure and performance of graphene so that industry can have security of supply, ensure successful applications and strengthen future investments in the technologies that utilise this material.”

Swinburne researchers have analysed the complete graphene supply chain – from production to industry practice. They have investigated graphene’s properties and tested its ability to combine with other materials in engineering developments, as well its potential to be used as a thin, protective coating. 

Graphene+ 2019

The use of graphene in the development of smart cities will be high on the agenda at the 2019 Graphene+ conference.

Other topics to be discussed include:

• Upgrading sensing equipment for the Internet of Things (IoT)
• Creating stronger, lightweight architectural structures using the latest in robotics technology
• Commercialisation of one-step water purification systems to make drinking water universally available
• Enhancing the harnessing and conserving of energy
• Jobs of the future – how will graphene change the industry?

Researchers will share knowledge and discuss the potential of advanced, sustainable and cost-effective technologies, contributing to the establishment of cities that thrive on smart devices and infrastructure.

Professor Fox will also chair a session on the impact of smart factories on jobs and graphene supply chains.

“We are fortunate to have some world-leading local and international speakers. The discussions will give us a glimpse of what the future might look like with graphene at the forefront of technology.”

• The wonder material is yet to live up to its potential but an Indian startup is weaving dreams with this form of carbon

The molecule is priceless, but it’s not the cost — a few lakh rupees per kilo — that helped graphene win the epithet of “wonder material” or “possibly the most remarkable substance discovered” in scientific circles.

Graphene owes its impressive resume to its multiple attributes — strong, flexible, light, transparent, waterproof and a good conductor of electricity. Ever since it was discovered in 2004, scientists have been speculating about its potential uses — replacing silicon in electronics, indium in touchscreens and liquid polymer in bulletproof vests. Unfortunately, the wonder material has failed to deliver on its promises and still has a long way to go.

Despite that, scientists and entrepreneurs haven’t stopped pumping billions of dollars and man hours into the quest for new inventions with graphene that can transform sectors such as electronics, energy, health and construction.

Log 9 Materials, a Bangalore-based nanotechnology start-up, has been chasing the graphene dream since it was founded in 2015 by IIT-Roorkee graduates Akshay Singhal and Kartik Hajela. It has been trying to tame the material in many avatars — cigarette filters, batteries for electronic vehicles and coatings for aircraft. Their latest foray is into industrial clean up, including oil leaks and oil spills. Liquid petroleum often gets accidentally released into oceans, bays and rivers during transport and the spill does irreparable damage to aquatic life.

“The oil sorbent pads (LSP 20) innovated by us help contain and absorb off-shore and on-shore [oil] spills as well as spills of other chemicals,” says Akshay Singhal, co-founder and chief executive officer of Log 9 Materials. “LSP 20 is able to absorb spills up to 86 times its own weight. It has been tested against British Standards by third party laboratories and has also been certified safe to incinerate and dispose,” he adds.

There is always a risk of spillage during exploration, transportation and storage of oil. Spills have the potential to cause irreparable ecological damage in sea and on land. In situ combustion, oil booms and oil skimmer vessels are used to clean up such spills but are not very efficient. The products and particulates emitted through oil combustion pollute the atmosphere while booms and skimmers, which are meant to confine the spill to a specific location for collection, do not work well in turbulent water.

One of the most economical and efficient means of removing oil spills is to use sorbents that repel water (hydrophobic) but absorb oil (oleophilic).

One of the most efficient means of removing oil spills is to use sorbents that repel water but absorb oil

Various natural absorbers such as expanded perlite and zeolites, organic materials such as wool fibre, activated carbon and sawdust have all been used as sorbents because of their extremely small pores. However, these materials are incapable of absorbing oil without the water. That is why new materials are needed that can sequester oil and remove it. Various microporous polymers have been studied due to their large specific surface area and hydrophobicity. Although they show relative high absorption ability, the cost of these kinds of sorbents is also high.

Graphene, discovered at the University of Manchester, UK, in 2004, consists of thin flakes of carbon atoms arranged in a hexagonal structure. It has a high surface area. While a typical carbon atom has a diameter of about 0.33 nano metres, there are about three million layers of graphene in 1mm of graphite — a crystalline form of the element, carbon. Harder than diamond but more elastic than rubber, tougher than steel yet lighter than aluminium, it can be processed into various unique structures. Several graphene-based structures have been designed and fabricated over the past decade to strongly repel water (superhydrophobic) but absorb oil (superoleophilic) efficiently. These characteristics make graphene an ideal candidate for selective absorption of oil spills.

“We manufacture products to control spills of all forms, using graphene. These products can be used to prevent, control and clean spills in and around marine or terrestrial ecosystems,” says Dhananjay Sharma, director and chief executive officer, Log 9 Spill Containment Pvt. Ltd.

“The company has a larger agenda to educate various industries and businesses about the value propositions attached to using graphene-based products or offerings with respect to cost savings and environmental impact,” he adds.

While graphene has countless potential applications, Log 9’s focus is on two main areas: filtration and energy. Apart from the oil sorbent pad, they are currently working on a metal-air battery which could replace the current lithium ion batteries.

Says Singhal, “This battery makes use of the interaction of air, water and aluminium. The air cathode made of graphene generates electricity, thus making it lighter in weight compared to lithium ion batteries.” Moreover, these batteries can run about 1,000km on a single charge compared to 100-150km of the current ones.

Technology usually progresses at a slow pace. Swedish chemist Jakob Berzilius purified silicon in 1824 but it took more than a century for the semiconductor — used to run all modern electronic gadgets — industry to develop. Most of the components of today’s smartphones, from microprocessors to touchscreens, were also invented in the 1960s. It is, therefore, expected that it will take some time for more horizons to open up in the world of graphene. It is laudable that an Indian start-up has dared to join graphene’s innovation race.

A study found that insects changed their behavior around the material.

Graphene, the highly flexible supermaterial used to build solar cells (and perhaps one day foldable phones), is also a powerful mosquito repellent. A team of researchers at Brown University discovered that graphene-lined clothing not only is an effective physical barrier to mosquito bites, the carbon-based material also changes their behavior. The study, which was published this week in the Proceedings of the National Academy of Sciences, found that graphene blocked the chemical signals that draw mosquitoes to other living beings in the first place.

“With the graphene, the mosquitoes weren’t even landing on the skin patch — they just didn’t seem to care,” said Brown Ph.D student Cintia Castillho, who is the study’s lead author. “We had assumed that graphene would be a physical barrier to biting, through puncture resistance, but when we saw these experiments we started to think that it was also a chemical barrier that prevents mosquitoes from sensing that someone is there.” In the study, researchers covered the arms of participants in either graphene oxide films covered by cheesecloth or just cheesecloth. Those who were covered in graphene didn’t receive a single bite.

Unfortunately, graphene oxide becomes far less effective when wet, which is exactly the type of environment where mosquitoes thrive. Scientists found that mosquitoes were able to puncture through graphene oxide films that were soaked in water. But when they used graphene with reduced oxygen content (rGO), they discovered it worked as a bite barrier in both dry and wet conditions.

One drawback is that rGO isn’t breathable, so it’s unlikely to be used in camping clothing. Scientists hope to find a way to stabilize graphene so it remains strong when wet. “This next step would give us the full benefits of breathability and bite protection,” said Brown University professor Robert Hurt.

If you’re curious about graphene, you won’t have long to wait. Makers of outdoor gear and electronics are already adding graphene to jackets, battery packs, shoes and more.

• Smartphones and portable electronic devices are omnipresent in the world we live in today. We rely heavily on these gadgets to complete a wide range of daily tasks from simple reminders and calendar events to more complex assignments and applications as powerful business tools.

• At some point in the day, we will find ourselves rushing around a room searching for a plug or USB socket as a cable dangles from our hands because the lithium-ion batteries that currently power our devices still only hold a limited charge.

However, frustrations such as this could soon be a thing of the past. According to the reliable tech-tipster Evan Blass, Samsung is gearing up to a 2021 launch of their usually hotly anticipated Galaxy series to come equipped with a more efficient longer-lasting graphene battery.

On Monday, Evan Blass tweeted, “Samsung is hoping to have at least one handset either next year or in 2021, I’m told, which will feature a graphene battery instead.”

Capable of a full charge in under a half-hour, they still need to raise capacities while lowering costs.

Evan Blass

Graphene batteries are believed to be the optimal solution and alternative to the current generation of lithium-ion batteries on the market. With higher electrical and heat conductivity compared to lithium-ion solutions, graphene is also superior due to its lightweight, flexible and durable qualities. For these reasons, we can begin to understand why graphene has been hailed as a ‘wonder material’.

So, what would be the benefits of using the material graphene as an alternative to lithium-ion in battery packs?

Slimline solutions: having already discussed how graphene is lightweight, we should also consider that when you stack 3 million layers of this material, it only amounts to 1 mm of thickness. This could mean that manufacturers can place small high-capacity batteries in devices to reduce the overall size of the device for compactness or enhance other capabilities and overall performance.

Faster charging times: this increases the battery endurance compared to lithium-ion batteries as the conductivity capabilities of graphene offers little to no resistance to the flow of electrons.

Reduced thermal output: because of its ability to dissipate heat much more effectively, graphene can reduce the operating temperature of smart devices. This means better performance and safety when charging or operating the device for complex tasks or gaming.

These may be of particular interest to a company like Samsung who have previously been affected by battery issues, particularly concerning the overheating issues of the Note7 back in 2016. This led to Samsung implementing an eight-point inspection process for batteries as well as stepping up its research into battery technology, making significant progress in recent years.

We need only look back to 2017 when Samsung revealed its researchers developed a “graphene ball” material capable of five times faster-charging speeds than standard lithium-ion batteries. Coupled with Blass’s latest claims, it is plausible to expect that we will see graphene batteries go mainstream within the next couple of years.

With products likely restricted to select smartphones and smart devices initially, we can also anticipate further developments on other applications for graphene in the coming years. For example, Tesla are showing interest in metal-air batteries which utilize a graphene rod as a cathode. These types of battery can increase battery efficiency up to five times at just one-third of the cost and because of the greater abundance of carbon, compared to a rare metal like lithium, manufacturers will continue to research its potential as they have been trying to implement the use of graphene as a material in about everything since its discovery in 2004.

So, it would suffice to say that graphene batteries are definitely set to be a game-changer and put an end to panicked searches for a place to charge devices or carrying around multiple charging packs to get through a busy day.
