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 use graphene oxide to develop devices that could advance future cellular therapy for multiple sclerosis patients

A team from the National Hospital for Paraplegics (SESCAM), in collaboration with the Materials Science Institute of Madrid (ICMM-CSIC), has shown how new cell culture devices based on graphene oxide maintain the anti-inflammatory function of myeloid suppressor cells (MDSCs) once isolated from the donor's body. This function could be crucial for advancing cellular therapy beneficial to people with multiple sclerosis. 

"To exert their inflammation-controlling function in diseases such as multiple sclerosis, myeloid suppressor cells must maintain a very immature state. However, when extracted from the bone marrow and cultured in the laboratory, they begin to mature, losing their immunosuppressive activity, rendering them unsuitable for potential cellular therapy for patients with this type of neurodegenerative disease," explains Diego Clemente, a researcher at the National Hospital for Paraplegics and one of the lead authors of the study.

Researchers design a butterfly-inspired multisensory neuromorphic platform for integration of visual and chemical cues

It is a known fact that animals require the integration of cues collected from multiple sensory organs to enhance the overall perceptual experience and thereby facilitate better decision-making in most aspects of life. However, despite the importance of multisensory integration in animals, the field of artificial intelligence (AI) and neuromorphic computing has primarily focused on processing unisensory information. This lack of emphasis on multisensory integration can be attributed to the absence of a miniaturized hardware platform capable of co-locating multiple sensing modalities and enabling in-sensor and near-sensor processing.

In their recent study, researchers at Penn State University addressed this limitation by utilizing the chemo-sensing properties of graphene and the photo-sensing capability of monolayer molybdenum disulfide (MoS2) to create a multisensory platform for visuochemical integration.

Researchers create graphene-integrated bioelectronic mesh for tracking multimodal excitation-contraction dynamics in cardiac microtissues

Researchers at the University of Massachusetts and Massachusetts Institute of Technology (MIT) have successfully built a tissue-like bioelectronic mesh system integrated with an array of graphene sensors that can simultaneously measure both the electrical signal and the physical movement of cells in lab-grown human cardiac tissue.

The tissue-like mesh can grow along with the cardiac cells, allowing researchers to observe how the heart’s mechanical and electrical functions change during the developmental process. The new device can be extremely useful for those studying cardiac disease as well as those studying the potentially toxic side-effects of many common drug therapies.

Levidian unveils graphene-enhanced prototype truck tire

Levidian has unveiled its first prototype truck tire, combining graphene with carbon black in a new tread formulation. Launched this week at the Tire Technology Expo in Hannover, the graphene-enhanced natural rubber and butadiene rubber tire tread compound, typically used in commercial vehicle tires, has been shown to deliver significant improvements in the mechanical and dynamic properties of the tire.

Independent testing by the Tun Abdul Razak Research Centre (TARRC) has reportedly shown that the addition of Levidian’s 'net zero graphene' can deliver a reduction in rolling resistance of around 23%. Initial results have also indicated potential for reduced compound density that could allow for lighter tires overall. It was said that overall, this could deliver substantial improvements in fuel efficiency of 3-4%.
