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.

HydroGraph Clean Power has announced that its flagship graphene product, FGA-1, has been successfully trialed in Hawkeye Bio’s biomedical sensor aimed at the early detection of lung cancer. Hawkeye Bio is a clinical stage medical technology company focused on the early detection of cancer.
HydroGraph’s graphene was selected by Hawkeye Bio based on the purity and consistency of its graphene. Headquartered in Toronto, HydroGraph’s manufacturing facility is located in Manhattan, Kan.
Earlier this year, Stolt Tankers entered an agreement with Graphite Innovations & Technology (GIT) for graphene-based marine coating to be applied on 25 ships. Now, Stolt Tankers has announced it is the first shipping company to apply a cutting-edge sustainable coating to the hull of one of its chemical tankers, Stolt Lotus.
The X-GIT FUEL graphene technology, developed by Graphite Innovation & Technologies (GIT) Coatings, has the potential to reduce fuel consumption and resulting greenhouse gas emissions. X-GIT FUEL is a hard foul release hull coating that creates an ultra-low friction surface to increase vessel performance, without the use of biocides, silicon oils or toxic components. The coating is expected to provide fuel savings of between five and seven percent by decreasing the friction between the hull and the water and removing marine growth as the ship travels.
Researchers at North Carolina State University and Pacific Northwest National Laboratory have found that graphene can enhance an important property of metals called the temperature coefficient of resistance.
They showed that mixing graphene in just the right proportion with copper could lead to improved electrical wires for more efficient electricity distribution to homes and businesses, as well as more efficient motors to power electric vehicles and industrial equipment. The team has applied for a patent for the work, which was supported by the Department of Energy (DOE) Advanced Materials and Manufacturing Technologies Office.
Directa Plus has revealed that it has signed a deal with an unnamed Italian innovator to buy the technology for a system capable of preparing tailored graphene compounds. According to the Company, this technology will initially be used in batteries and polymers.
It explained that the acquired know-how and technology would help to enable the dry encapsulation of G Plus graphene nanoplatelets into different compound carriers for different exacting applications.
A new Horizon Europe funded project was launched in October 2023. With a consortium of 11 partners from 8 different countries, the Next-2Digits project aims to develop the next generation of sensors and imagers enabled by 2D materials digital integration. Next-2Digits will run for 3 years and 3 months.
Coordinated by the National Technical University of Athens, Next-2Digits benefits from the presence of academic, research and industrial teams, whose areas of work span from graphene and 2D materials synthesis, characterization, manipulation, and integration, as well as in the fields of photonics, material science, application-based integration technologies and validation.
HydroGraph Clean Power has announced successful testing of its flagship product, FGA-1, fractal graphene, in electromagnetic interference (EMI) shielding.
The integration of HydroGraph’s graphene in epoxy resin was reportedly able to achieve substantial EMI shielding properties by reaching an 80-decible (dB) attenuation (a reduction of signal strength during transmission) in shielded enclosures of less than 1 mm thick. Minimum ratings for consumer protection are 30 dB and ranges from 60 dB to 80 dB for automotive and aerospace applications.
Researchers from Korea's Seoul National University and Sungkyunkwan University recently developed a method to grow GaN LED arrays on a flexible graphene layer. The so-called microdisk arrays exhibit excellent crystallinity with a uniform in-plane orientation and strong blue light emission.

The researchers grew the GaN microdisks on a graphene layer (grown on a sapphire substrate) covered with a micro-patterned SiO2 mask using metal–organic vapor-phase epitaxy. The microdisks were then processed into micro-LEDs and then successfully transferred onto bendable substrates.
Researchers at Flinders University, Flinders University and Birmingham City University are developing a 'value add' approach for old broken concrete for 'upcycling' coarse aggregate to produce a strong, durable and workable concrete using graphene.
The scientists have tested results using a weak graphene solution on recycled aggregates to produce concrete potentially superior to untreated recycled aggregates in cement-based mixtures.
Ora Graphene, producer of free-standing graphene membranes, announced a partnership with Taiwan-based Merry Electronics to develop off-the-shelf GrapheneQ headphone drivers. These, according to Ora, will be the world's first commercially available graphene-based drivers. The two companies will offer 40 mm and 50 mm drivers, which will be available for pre-order in Q1 2024.
Ora Graphene says that it already integrated its technology into flagship products for two major consumer electronics companies - both of these premium gaming headphones. The availability of off-the-shelf headphone drivers will hopefully accelerate the adoption of Ora's technology.
