Magnetic field-assisted fabrication of quasi-bilayered, multi-responsive and patternable actuators.

Quasi-bilayered actuators composed of FeO-decorated graphene oxide and polyvinylidene fluoride have been fabricated in a magnetic field. The actuators could stably respond to multiple stimuli including infrared light, acetone vapour and a magnetic field. The actuator is also patternable because of the magnetism-induced spatial distribution of fillers in the matrix.
