Graphene applications: what is graphene used for?

Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb-like pattern. Graphene is considered to be the world's thinnest, strongest and most conductive material - of both electricity and heat. All of these properties are exciting researchers and businesses around the world - as graphene has the potential to revolutionize entire industries - in the fields of electricity, conductivity, energy generation, batteries, sensors and more.

Mechanical strength

Graphene is the world's strongest material, and can be used to enhance the strength of other materials. Dozens of researchers have demonstrated that adding even a trace amount of graphene to plastics, metals or other materials can make these materials much stronger - or lighter (as you can use a smaller amount of material to achieve the same strength).

Such graphene-enhanced composite materials can find uses in aerospace, building materials, mobile devices, and many other applications.

Thermal applications

Graphene is the most heat conductive found to date. As graphene is also strong and light, it means that it is a great material for making heat-spreading solutions, such as heat sinks or heat dissipation films. This could be useful in both microelectronics (for example to make LED lighting more efficient and longer lasting) and also in larger applications - for example thermal foils for mobile devices. Huawei's latest smartphones, for example, have adopted graphene-based thermal films.

Energy storage

Since graphene is the world's thinnest material, it also extremely high surface-area to volume ratio. This makes graphene a very promising material for use in batteries and supercapacitors. Graphene may enable batteries and supercapacitors (and even fuel-cells) that can store more energy - and charge faster, too.

Coatings ,sensors, electronics and more

Graphene has a lot of promise for additional applications: anti-corrosion coatings and paints, efficient and precise sensors, faster and efficient electronics, flexible displays, efficient solar panels, faster DNA sequencing, drug delivery, and more.

Graphene is such a great and basic building block that it seems that any industry can benefit from this new material. Time will tell where graphene will indeed make an impact - or whether other new materials will be more suitable.

Researchers develop method to create stretchable and tough graphene films

Researchers have been working on creating elastic and tough graphene films, but it has proven quite challenging so far. Now, researchers at Shanghai Jiao Tong University have introduced a method to overcome this hurdle: they linked graphene nanolayers via "extendable" bridging structures.

The special properties of graphene nanolayers often drop off when the layers are assembled into foils, because they are only held together by relatively weak interactions—primarily hydrogen bonds. Approaches that attempt to improve the mechanical properties of graphene foils by introducing stronger interactions have only been partially successful, leaving room for improvement in the stretchability and toughness of the materials. The research team, led by Xuzhou Yan at Shanghai Jiao Tong University in China, chose a new approach: they cross-linked graphene nanolayers with mechanically interlocked molecules whose building blocks are not chemically linked, but rather inseparably spatially entangled. The researchers used rotaxanes as their links.

Gerdau Graphene launches 'NanoCORR Shield' graphene-enhanced anti-corrosion additive for solvent-based paints

Gerdau Graphene has announced the availability of NanoCORR Shield, the newest product from its G2D NanoCORR line of anti-corrosion paints and coatings additives. Developed with Gerdau Graphene's exclusive G2D technology, NanoCORR Shield is a graphene-enhanced chemical additive designed to increase the corrosion resistance of solvent-based paints and coatings. NanoCORR Shield has demonstrated a 30-70% increase in corrosion resistance when subjected to salt spray testing.

The addition of a small amount of specially-developed graphene into paints and coatings allows for an increase in the barrier effect against corrosive elements such as water, oxygen, and chlorides. In addition, NanoCORR reduces paint consumption by reducing the nominal thickness of the coating while maintaining the paint or coatings' other characteristics and performance properties.

Researchers develop new approach for controlling thermal emission

Researchers from the University of Manchester, The Pennsylvania State University, Koç University and Vienna University of Technology (TU Wien) have tackled the challenge of control of thermal radiation, demonstrating a new topology-based approach.

The team explained that conventional approaches to tailoring thermal emission using metamaterials are hampered both by the limited spatial resolution of the required subwavelength material structures and by the materials’ strong absorption in the infrared. In their recent work, the scientists developed an approach based on the concept of topology: by changing a single parameter of a multilayer coating, they were able to control the reflection topology of a surface, with the critical point of zero reflection being topologically protected.

Researchers develop graphene-based battery-free lactic acid sensor

Scientists at the University of Bath, working in collaboration with Integrated Graphene, have created a new type of chemosensor (demonstrated for lactic acid sensing) which functions with electricity but without the need for reference electrodes or battery power. The new design potentially offers lower cost, better shelf-life, and ease of miniaturization compared to enzyme-based sensors. This could open up the possibility for an easy-to-use sensor to be used in remote locations, such as an athletics track, without the need for electricity-powered sensing equipment.

The sensor was able to detect lactic acid, a by-product generated by the body when it metabolizes carbohydrates or glucose for fuel, for example, during exercise. High levels of lactic acid are linked with higher risks of falling unconscious or into a coma and major organ failure.
