GF01 - Standardisation

Motivation
In order to drive products based on graphene and related materials (GRMs) to the market, standardized techniques for assessing and classifying GRMs are necessary. As GRMs usually feature multimodal properties (polydispersed sheet or grain size, density of defects, different oxidation grades, different mono- bi- few layers fractions,  etc.), it is mandatory to define standard procedures to measure their porperties and to ensure consistent and repeatable quality of material in the market for different applications. Thus, any classification standard needs to be application driven, with parameters and properties tailored to the applications and measurement/assessment methods relevant for the end-use of the material.  Such a classification system would allow grading the material. Well defined methods to measure the relevant properties of GRMs will, therefore, need to be standardized to avoid ambiguity for end users and customers.

Complementarities are envisaged with WP11(Production), WP1(Materials), WP3(Fundamental Science). Applicants must have a proven track record in the development of standards for industrially applied materials. All basic know-how in identification and characterisation of GRMs is present already in the Flagship. Proposal must demonstrate a feasible plan to create a standard, by combining the specific know-how of the applicants with that already present in the Flagship.

Objectives

  • To achieve a reliable “toolbox” for GRM standardization. This may include the combination of structural characterization by local Raman, transmission-reflection measurements,  microscopy (SEM, STM,AFM,EFM,TEM), Xray diffraction etc., as well as electronic transport measurements and magnetotransport, or any other technique that has been proven useful in assessing the chemical quality of GRMs (XPS, EELS, etc.), with the appropriate choice for the application targeted for. 
  • Standard procedures defining the measurement conditions, data treatment, interpretation tools
  • Post-growth methods for quality control and industrial in-line monitoring.
  • To create a connection with similar major European standardization initiatives, as well as with major Non-European efforts, such as those in Asia, USA, and Japan.

Impact

  • Design of appropriate policies for workers and environment protection, as well as for the registration of GRM-based products.
  • Standard procedures will enable the direct comparison between GRMs and devices produced by the different institutions.
  • Speed up of optimization of growth processes with in-line standardized characterization for mass production.
