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 - to both electricity and heat. All this properties are exciting researchers and businesses around the world - as graphene has the potential the revolutionize entire industries - in the fields of electricity, conductivity, energy generation, batteries, sensors and more.
Graphene is the world's strongest material, and so can be used to enhance the strength of other materials. Dozens of researches have demonstrated that adding even a trade amount of graphene to plastics, metals or other materials can make these materials much stronger - or lighter (as you can use less 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 world's most conductive material to heat. As graphene is also strong and light, it means that it is a great material to make heat-spreading solutions, such as heat sinks. 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.
Because graphene is the world's thinnest material, it is also the material with the highest surface-area to volume ratio. This makes graphene a very promising material to be used in batteries and supercapacitors. Graphene may enable devices that can store more energy - and charge faster, too. Graphene can also be used to enhance fuel-cells.
Coatings ,sensors, electronics and more
Graphene has a lot of other promising 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:
Elcora Advanced Materials has announced it has entered into a research and development agreement with Solargise Canada, a solar manufacturing and utility-scale power project development company.
The scope of work of the research and development agreement includes the development of new technologies using graphite and graphene to improve and augment the efficiency of the solar photovoltaic panels manufactured by Solargise.
Graphene Flagship partner, Emberion, will be launching a VIS-SWIR graphene photodetector at Laser World of Photonics, from 24 to 27 June in Munich, Germany. The linear array covers a wide spectral range, detecting wavelengths from the visible at 400nm into the shortwave infrared up to 1,800nm. Traditionally, it would require both silicon and InGaAs sensors to image across this wavelength range.
Emberion estimates that replacing a system using silicon and InGaAs sensors with its graphene photodetector would result in a 30% cost reduction.
Researchers at Joseph Wang's Laboratory for Nanobioelectronics at UC San Diego demonstrated the synthesis of high-performance stretchable graphene ink using a facile, scalable, and low-cost laser induction method for the synthesis of the graphene component.
As a proof-of-concept, the researchers fabricated a stretchable micro-supercapacitor (S-MSC) demonstrating high capacitance. This is said to be the first example of using laser-induced graphene in the form of a powder preparation of graphene-based inks and subsequently for use in screen-printing of S-MSC.
Graphene Leaders Canada (GLC) has announced that it has been awarded $350,000 CAD (around $261,000 USD) grant funding for a joint project under the National Research Council – United Kingdom (UK) Research Institute (NRC-UKRI) Research and Innovation Program. This funding will support GLC’s “Scaling of Graphene Oxide” towards the development of GLC’s Environmental platform of products.
“This project will support scale up activities of graphene oxide with a focus on developing a cost effective, scalable production method aimed at commercializing our environmental platform of products for air and water treatment,” said Dr. Leah Coumont, GLC’s Director of R&D.
Verditek and Paragraf have announced that they have successfully applied graphene to a photovoltaic (PV) cell as part of a joint development program (JDR) and are now continuing work with the goal of surpassing 25% efficiency.
London-based clean technology company Verditek explains that as part of the partners’ first development project they applied Paragraf's graphene manufacturing process to Verditek's solar technology to produce a working proof-of-concept silicon/graphene integrated solar cell. As a next-stage project, they will aim to boost the performance of the cells, develop the opportunity to file patents and possibly initiate commercial discussions for industrial manufacture and application.
