“Graphene Preparation” Research on a new generation of graphene products at Uppsala University, Sweden

In the large-scale production of graphene raw material products, graphene flakes tend to be heavily viscous, causing it to lose its unique properties and return to its native graphite state. Researchers at Uppsala University in Sweden have developed a new type of graphene that can solve the problem.

Graphene has many incredible properties, but so far it has been difficult to use it on a large scale in the industry. When produced on a large scale, the graphene flakes have a tendency to re-bond, causing it to lose its unique properties and return to the native graphite state. Mamoun Taher, a researcher at Uppsala University in Sweden and CEO of startups Graphmatech, has developed a new type of graphene that can solve the problem.

The new material Aros Graphene is designed to prevent this by combining design molecules, so-called “separators”. Graphmatech says: “The separator is designed to separate graphene sheets without degrading their performance, so we can control the material. This process is designed to be environmentally friendly, we use water as a solvent and do not use hazardous chemicals. The most striking finding is that we have produced a new material, but we have discovered the amazing properties of this new material. It has been proven that ArosGraphene® not only has the electrical and thermal properties of graphene in two dimensions but also in three dimensions, and that the surface has extremely low friction and high wear resistance.

ArosGraphene® is a hybrid ion graphene material that is being used in applications that can be used as an additive for substrates, coatings or even 3D printing. The product has been proven in preliminary tests by potential customers. This is the first commercial application to be launched in 2019.

Company said: “We have seen that thermal conductivity paste containing Aros graphene has higher thermal conductivity than other thermal paste products on the market. 180%. In the near future, more and more data centers will be needed to store data, and there is a huge demand for advanced thermal management solutions. ”

GraphMaTech has several other projects, such as self-lubricating mechanical systems, mobile electrical contacts and printed supercapacitors.
