本文件规定了用一系列测量技术表征石墨烯、双层石墨烯和石墨烯纳米片结构特性的方法序列，这些方法通常是在基板上分离出单个薄片后，从粉末和液体分散体中提取。所涵盖的特性包括层数/厚度、横向薄片大小、无序程度、层排列和比表面积。给出了从粉末和分散体中表征石墨烯的建议测量方案、样品制备程序和数据分析。

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 the isolation of individual flakes on a substrate. The properties covered are the number of layers/thickness, the lateral flake size, the level of disorder, layer alignment and the specific surface area. Suggested measurement protocols, sample preparation routines and data analysis for the characterization of graphene from powders and dispersions are given.
