Round Robin 2019

Important results from the project

There are many variants of graphene and not all suppliers specify the material in an equivalent way. The availability of quality-assured graphene has therefore proven to be one of the biggest challenges for the continued development of the graphene area in recent years. The purpose of the project was therefore to develop and evaluate characterization methods of graphene that can work in industry. A simple guide for how four different characterization methods can be used has been developed.

Expected long term effects

The many different types of graphene can lead to different properties of the end product. It is therefore important to characterize the graphene used. This project has increased the understanding of which characterization methods of graphene are industrially viable and what results these give. The project has increased the knowledge about graphene characterization among more actors and with more analysis methods. With more knowledgeable analysis providers spread across Sweden, the availability of these important analyzes increases.

Approach and implementation

Swedish analysis suppliers could apply for a grant to analyze six different graphene materials with dynamic light scattering (DLS), Raman, scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Former project managers for projects within SIO Grafen were able to influence which graphene materials were investigated. These materials were purchased by SIO Grafen´s program office and redistributed in anonymous containers and then distributed to the analysis suppliers. The different methods were evaluated with respect to the industrial use of graphene.
