62 Programmable actuation of porous poly(ionic liquid) membranes by aligned carbon nanotubes
关键字：actuators poly(ionic liquids) porous membranes programmable bending
A porous composite membrane, combined poly(ionic liquids) with aligned carbon nanotubes that shows anisotropic actuation toward organic solvent is developed. The membrane actuator shows rapid and reversible actuation in response to acetone vapor as well as improved conductivity. These properties allow the composite membrane to be organic solvent‐induced actuator as well as a power switch.
