Nanotechnologies — Structural characterization of graphene oxide flakes: thickness and lateral size measurement using AFM and SEM

Scope

This document describes methods for measuring the lateral size and thickness of graphene oxide (GO) flakes using scanning electron microscopy (SEM) and atomic force microscopy (AFM) respectively, including sample pre-treatments, measurement procedures and data analysis. It is applicable to the characterization of graphene oxide in powder and liquid dispersion forms.
