The reversible stimulus-responsive volume change in graphene materials has never been realized, due to the irreversible restacking or agglomeration of graphene sheets. In this study, the graphene-polymer hydrogel with reversible volume changes has been prepared by a hydrothermal method. It has good electrical conductivity, high mechanical strength and a tunable electrical conductivity. The hydrogel exhibits reversible volume changes in response to an electric current, which makes it a potential candidate for artificial muscle devices. (C) 2012 Elsevier Ltd. All rights reserved.
