TWA 41

Graphene and Related 2D Materials

Due to its many exceptional properties, graphene is predicted to impact many different industry application areas such as solar cells, biosensors, displays, composites, flexible electronics and energy storage. As industry uptake on this material increases, standardization will be increasingly required to enable commercialization. Particularly important for its uptake is the reliable, accurate and reproducible measure of the different properties of the material. This is because there are issues with both differing routes of production and batch-to-batch consistency.

The objective of this TWA will be to validate different methodologies of measurement for graphene and related 2D materials. Determining the uncertainties associated in measurement, sample preparation, and data analysis. Interlaboratory studies will be conducted and the results will form the basis for future standardisation.
