This paper first fabricated palladium type ionic polymer-metal composite material(Pd-IPMC),explored that the water content within in IPMC had a detrimental effect on the relaxation property,then IPMC was packaged by polydimethylsiloxane and polytetrafluoroethylene based on it.The IPMC was packaged by polydimethylsiloxane and polytetrafluoroethylene,which indicated a good stable performance without relaxation phenomenon and a quick response.The good performance of IPMC can be stable.The method by packaged with polydimethylsiloxane and polytetrafluoroethylene solved the difficult problem for the material are used for actuators and established the foundation for its application.
