Tailor made graphene production

Important results from the project

In the process that 2D fab uses in the production of graphene, there is a potential for improvement primarily with regard to yield and quality. In this project, the goal has been to improve these parts but also to reduce the energy input. Being able to produce the graph adapted to the wishes of different customers was also an important parameter in the project. The results of this project have shown great progress.

Expected long term effects

2D fab´s process for the industrial production of graphene has with this project taken a step forward. In collaboration with Valmet, we have taken the process to a higher level in terms of quality and yield with reduced energy input. Together with MiUn and Valmet, new knowledge for design of new fittings has been developed. I a subsequent step with hydrocyclones, a well-functioning graphene separation has been developed. The result of the project is thus that the exfoliation process is more efficient and that separation of different customized graphene qualities can now be produced.

Approach and implementation

The project started by identifying and testing two existing tools with different designs for exfoliation. These two tools have since been adapted to work in our process. Based on these experiments, a tool has given better results. Simulation exercises in a computer environment have been conducted to further provide information about the "ultimate" tool. The produced material has been taken to the next process step to separate the graphene from a graphene / graphite slurry. Various produced qualities must then be evaluated for reduced wear in ball bearing seals.
