THE EFFECT OF CARBON FILLER TYPE ON ACTUATION BEHAVIOROF CONDUCTING POLYMER ACTUATOR

摘要

Conducting polymer (CP) actuators undergo a volume change as the redox state is changed. The volume change is caused by the movement of counter ions into the film during the electrical oxidation process. In freestanding CP actuators, the electrical resistance of a CP film can produce significant power-supply voltage (IR) drop along its length, which can restrict the actuator performance. To solve this problem, CP nanocomposite with carbon filler was introduced. This study aimed to improve conductivity and ease off the IR drop occurred during the actuation of CP actuator. CP nanocomposite actuator with 3:7 of CB:CNF co-filler content showed the maximum displacement due to the synergy effect, and did not involve IR drop when the length of actuator was 25 mm.
