摘要：
Current-voltage characteristics of graphene oxide (GO) films were explored in water vapor as a function of film water content. It has been found that the films under study may contain free and bound water that can be completely eliminated in vacuum. A new phenomenon - a decrease in current with time at a constant voltage - was revealed. This was associated with elimination of water in the absence of electrochemical processes. The theoretical model was suggested to rationalize the behavior of water diffusivity in the process of electroconductivity. (C) 2016 Elsevier B.V. All rights reserved.
