Electrical Coating Method of Graphene Oxide

Abstract

In this work, we use the electrical method to coat graphene oxide (GO) on ITO (Indium Tin Oxide) glass. The coated GO was characterized by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). The coated surface was monitored by scanning electron microscope (SEM) and atomic force microscope (AFM). Based on this coating method, we can control the thickness of GO film by changing the applied voltage. Result of thickness control was analyzed by AFM and transmittance measurement. Also this method can selectively deposition of GO film is possible on patterned ITO. This result was confirmed by Raman spectroscopic mapping.
