Works well on paper: Electromechanical actuators are constructed utilizing flexible pristine graphene paper and magnetic graphene/Fe3O4 paper. The resulting magnetic graphene paper presents higher actuation strain than pristine graphene paper and the obtained maximum strain reaches up to 0.1%. The dominant mechanism of the electromechanical actuation for the graphene-based paper involves quantum-chemical and double-layer-electrostatic interactions.
