This document specifies the sequence of methods for characterizing the structural properties of graphene, bilayer graphene and graphene nanoplatelets from powders and liquid dispersions, using a range of measurement techniques, typically after flake isolation. individual on a substrate. Properties covered are number of layers/thickness, lateral flake size, level of disorder, alignment of layers and specific surface area. This document also suggests measurement protocols, sample preparation procedures and data analyzes for the characterization of graphene from powders and dispersions.
