As a conductive polymer, polypyrrole (PPy) has many advantages such as non-toxic monomer, low cost and high conductivity. The conductive polymer actuator has low driving voltage and can be operated in water and air, and is widely used in biomedical equipment, bionic robots, sensors and some other fields. In this work, electrochemical deposition was adopted to deposit PPy membrane on PVDF polymer to construct conductive polymer actuators. The process parameters such as temperature and current density on the surface of PPy and actuating performance were optimized. It was found that the PPy films were uniform, compact and conductive when the deposition temperature was controlled between -25 and -30℃, the polymerization time was 10 h and the current density was 0.1 mA/cm². The displacement test platform of actuators was built by using micro laser sensor, data collector, electrochemical workstation and measuring microscope. Orthogonal experiments were carried out to investigate the actuating properties of PPy-based actuators, which showed that the tip displacement of actuators was proportional to their length and driving voltage; the wider actuators demonstrated increasing displacement. Furthermore, the process parameters were optimized from the angle of driving performance, which provided a complete parameter model for the optimal fabrication and practical application of PPy actuators. This study provides a theoretical basis for the application of PPy-based actuators in artificial muscles, sensors and actuators, and micro-nano manipulation systems.
