A series of nitric acid treated CFs were produced to explore surface heterogeneity. Several surface analysis techniques, SEM, XPS, AFM and Raman, were compared. Raman spectral maps were used to explore chemical effects of the treatments on CF. These maps provided information at a spatial resolution unattainable by XPS. CFs subjected to the harshest treatment displayed increased surface heterogeneity.
