The Graphene Flagship standardisation team works towards establishing consensus-based international standards in the field of graphene and related materials that will help stimulate innovation and market penetration.
The further commercialisation of materials and technologies based on graphene and related materials as well as the establishment of robust, underlying value networks remain a challenge. Industry has identified the lack of standardised materials, processes and characterisation impeding methods as one important factor slowing down innovation in the field.
GRAPHENE STANDARDISATION NEEDS AND BENEFITS
Industry has identified the lack of standardised materials and characterisation methods as one important factor slowing innovation in the field of graphene. The issue can be illustrated by two questions: “What properties of graphene or a related material do I need to know and control in order to reliably achieve the desired function in my application?” and “Who can guarantee that their raw material meets my specifications in every single production batch?” Already the first question is often surprisingly hard to answer, e.g., in case of polymer composites using graphene as a filler, where flake size, surface functionalisation, lattice defects, aggregation behaviour, material processing, and many other factors have a decisive impact on the performance of the composite. Finding the right supplier in such a case may be an additional challenge. Standardisation lays the basis for solving such issues. It will help enable better quality control, improve reliability and trust, and lower one of the key barriers to graphene innovation and commercialisation.
GRAPHENE STANDARDISATION TODAY
Work on standards in the field of graphene and related materials is focussed on
- Characterisation methods
- Sample preparation
- Data analysis
Over 35 projects leading to standards or technical specifications. Various measurement and characterisation methods are being addressed, including:
- Level of disorder, number of layers (Raman)
- Specific surface area (BET)
- Structural properties (TEM, SEM, AFM)
- Electrical properties (various methods)
Within accompanying projects (EMPIR, VAMAS), interlaboratory comparisons and round-robin tests are conducted, and new methods are developed.
