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.
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.
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.
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.
The latest Graphene Application news:
First Graphene will work with the Breedon Group, Morgan Sindall Construction & Infrastructure and the University of Manchester to develop a new reduced-CO2 graphene-enhanced cement. The consortium is currently formulating the cement using varying doses of First Graphene’s PureGRAPH graphene-enhanced grinding aid. The project received a research grant from the UK government earlier in 2022.
First Graphene says that the study involves one of the largest commercial trials of its kind to date globally.

NTT Corporation and the National Institute for Materials Science (NIMS) have jointly reported the realization of what they define as "the world's fastest zero-bias operation (220 GHz) of a graphene photodetector (PD)". The research conducted by NTT and NIMS has also, according to the statement, clarified the optical-to-electrical (O-E) conversion process in graphene for the first time.
Graphene is a promising photodetection material for enabling high-speed O-E conversion at wavelength ranges where existing semiconductor devices cannot operate, thanks to its high sensitivity and high-speed electrical response to a wide range of electromagnetic waves, from terahertz (THz) to ultraviolet (UV). However, until now, the demonstrated zero-bias operating speed has been limited to 70 GHz due to conventional device structure and measurement equipment. For this reason, the challenge for graphene PDs is to demonstrate 200-GHz operation speeds and clarify graphene's inherent properties, such the process of optical-to-electrical conversion.
Haydale and Atomi have announced they will be working together on a project aimed at developing high-performance, intelligent concrete. Using graphene and adding sensor technology, the next generation of strengthened concrete reportedly has the potential to reduce CO2 emissions by more than 30% while offering performance indicators during its lifetime thanks to intelligent sensors capable of capturing real-time data.
Graphene-enhanced concrete is a relatively new development but has been gaining traction and is already being tested around the world, including in several construction projects in the UK. To learn more about graphene-enhanced construction materials, don't miss Graphene-Info's new report.

Personal protection equipment maker, MCR Safety, recently introduced CT1071, a new Cut Level ‘E’ safety glove made with graphene fibers. It offers a choice of different coatings designed for different tasks and working environments. CT1071 has a 15-gauge shell specifically designed to take advantage of the ultra-lightweight nature of the new fibers. It’s a Cut Level ‘E’ glove yet it’s reportedly 25% lighter than similar gloves offering the level of protection. It is also designed to be comfortable and easy to wear.
As this fiber isn’t blended with any glass or steel, the high-level cut protection is maintained throughout the life of the glove. No fiber breakage means high durability, high comfort and no irritation. The diaphanous Nitrile Micro-Foam coating enables enhanced grip, even in oily conditions.
