This document specifies the sequence of methods for characterizing the structural properties ofgraphene, bilayer graphene and graphene nanoplatelets from powders and liquid dispersions using arange of measurement techniques typically after the isolation of individual flakes on a substrate. Theproperties covered are the number of layers/thickness, the lateral flake size, the level of disorder, layeralignment and the specific surface area. Suggested measurement protocols, sample preparation routinesand data analysis for the characterization of graphene from powders and dispersions are given.
