摘要
Over the past two decades,we have observed an explosive growth in the field of electroactive polymers(EAPs),polymers that respond to external stimuli by changing their shape or size or even when mechanically stressed produce a measurable charge[1-6].Specifically,the research on the ionic EAP,such as ionic polymer-metal composites(IPMCs),has attracted international attention.The IPMC material has the ability to function as an actuator or a sensor in both air and wet environments,and generally IPMCs require low voltages(<5 V)for actuation.When an IPMC is subjected to a voltage,deformation occurs due to the migration of ions and polar solvents within the polymer material.
