For the current flexible actuators, the long-term performance and the reusability usually cannot meet the practical standards, and the bending direction is usually not controllable. To address this issue, a complicated manufacturing process employed to produce a flexible actuator with desirable bending property and durability. Here, we report an easy-to-prepare and low-cost fabrication method for the preparation of PVDF/PEDOT:PSS/CNTs composite film as a multifunctional actuator. This actuator can generate significant bending when exposed to acetone vapors, and the bending direction is adjustable by orienting the carbon nanotubes on the surface. Furthermore, the actuator can produce voltages up to 90 mV via the piezoelectricity of the PVDF. Overall, our approach provides a simple and promising strategy for producing self-powered devices.
