Graphene as a material has many properties but is difficult to use on a large scale in industry. Now, however, a researcher from Uppsala University, Sweden, has developed a new generation of graphene that can solve the problem.
Graphene is a one atom thick two-dimensional carbon material. One disadvantage is that until now it has been difficult to use on a large scale as the material loses its unique properties and goes back to its origin, graphite. The new generation of graphene, Aros Graphene, has been designed to prevent this by incorporating designed molecules, so called ‘separators’.
Mamoun Taher, a researcher at the Department of Chemistry at Uppsala University and CEO of start-up company Graphmatech said: “The challenge has been to scale up graphene’s outstanding properties from nanoscale at laboratories to macro-scale at industry without degradation.
“The separators are designed to separate graphene flakes without degrading their properties, so we have control over the material. The process has been designed to be environmentally accepted, we use water as a solvent and no hazardous chemicals.”
Working alongside InnoEnergy, Taher’s start-up company began with applications in electronics and the telecommunication industry, and the new material can be used to efficiently dissipate heat from electronics which enables more compacted designs, longer life spam and safer operation.
Taher said: “We’ve seen that a thermal paste that contains Aros Graphene is 180% more thermally conductive than other thermal paste products on the market. In the close future where more and more data centres will be needed to store data, there is huge demand for advanced thermal management solutions.”
Graphene is the building block of the material graphite – pencil lead – and is an incredibly strong and conductive material. It can be used in a wide range of applications, including:
- Aerospace engineering;
- Digital electronics; and
Graphene is the strongest known material, over 200 times stronger than steel, yet it is also stretchy. It can conduct electricity and heat incredibly well, despite being only a single atom thick.
