Abstract :
A novel actuator has been fabricated using graphene and graphene oxide composite paper as building blocks. The two materials have nearly equal Young´s modulus, however a large displacement was observed during the electromechanically driven operation, which was attributed to great difference in coefficient of thermal expansion of graphene paper and graphene oxide paper.
