A bilayer “paper,” composed of adjacent graphene oxide and MWCNT layers each approximately 10‐µm thick, is fabricated by simple sequential filtration of an aqueous suspension of MWCNTs and then graphene oxide platelets, and demonstrated as the first case of a macroscopic graphene‐based actuator. The papers curl (see image) depending on humidity and/or temperature.
