A commercially available membrane filter paper composed of mixed cellulose esters bearing typically an interconnected pore structure is transformed into a stimuli‐responsive bilayer actuator by depositing a thin film of poly(ionic liquid)‐modified graphene oxide sheets (GO‐PIL) onto the filter paper. In acetone vapor, the as‐synthesized bilayer actuator bends readily into multiple loops at a fast speed with the GO‐PIL top film inward. Upon pulling back into air, the actuator recovers its…
