Abstract

A dry type conducting polymer actuator PEDOT/NBR/PEDOT is prepared. Nitrile rubber (NBR) containing room temperature ionic liquid, 1-butyl-3-methyl imidazoliumbis (trifluoromethylsulfonyl) imide (BMITFSI), have been utilized as a new type of solid polymer electrolytes. Various types of NBR having different amounts of acylonitrile (ACN), viz. 23, 35, and 40mol.%, are synthesized in order to examine the effect of polarity of NBR on the actuation behavior. A conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), was synthesized on the surface of the SPEs by using a chemical oxidative polymerization technique. The electrical potential was applied on PEDOT layer which caused volume change to result in actuation behavior. The characteristics of the PEDOT/NBR/PEDOT actuator were carefully examined.
