Abstract

ABSTRACTA modified Hummers method was used to synthesize graphene oxide (GO) with different degrees of oxidation. Single-factor and orthogonal experiments were designed to analyze the influence of the oxidant dose on the properties of the GO. The GO series were characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, elemental analysis, and zeta potential measurements. We synthesized RGO/PEDOT:PSS composites by an in situ polymerization with the GO. Through analysis of the specific conductance of the composites, we determined the optimum conditions for forming RGO/PEDOT:PSS which can improve the specific conductance to 114.06 S/cm. Thus, by changing the oxidation degree of GO we were able to improve the conductivity of RGO/PEDOT:PSS composites.
