Electroactive materials that change shape in response to electrical stimulation can serve as actuators. Electroactive actuators of this type have great utility in a variety of technologies including biomimetic artificial muscles, robotics and sensors. Electroactive actuators developed to date often suffer from problems associated with the need to use electrolytes, slow response times, high driving voltages and short cycle lifetimes. Herein, we report an electrolyte-free, single component, polymer electroactive actuator, which has a fast response time, high durability and requires a low driving voltage. The process employed for production of this material involves wet-spinning of a pre-organized camphorsulfonic acid(CSA) doped polyaniline gel, which generates long, flexible and conductive microfibers. Reversible bending motions take place upon application of an alternating current to the PANI polymer. Flapping wing motions were promoted under an external magnetic field by low voltages. |
