Specific Features of Temperature Dependence of Graphene Oxide Resistance

Abstract

Temperature dependence of graphene oxide resistance during continuous heating and cooling under argon atmosphere at 300–550 K and Raman spectra were studied. Resistance is constant within 300–370 K during cooling. It is thermostable under further heating. Temperature dependence of resistance changes according to activation law within 370–550 K. The decrease of resistance at the increase is related to the removal of functional oxygen-containing groups, which is proved by the results of Raman spectra.
