Novel electromechanical actuation based on a spongy graphene paper.
A spongy graphene paper with an inside foldable corrugated structure is fabricated by electrothermal reduction of the oxygen-containing groups inside an RGO paper. Reversible macroscopical length contraction of the spongy graphene paper with a strain of 2.4% under 10 V voltage is exhibited, mostly attributed to the deformation of corrugated structures.
