本文报道了在固体聚合物电解质中以丁腈橡胶（NBR）为基材制备干式导电聚合物致动器。采用化学氧化聚合技术在丁腈橡胶层表面合成了导电聚合物聚（3,4-乙烯二氧噻吩）（PEDOT）。将基于咪唑盐的室温离子液体（RTIL），如1-丁基-3-甲基咪唑X(其中X =BF4-, PF6-, （CF3SO2)(2)N-）吸收到复合膜中。通过DMA验证了离子液体与丁腈橡胶聚合物的相容性。考察了离子液体阴离子大小对致动器位移的影响。随着离子液体阴离子尺寸的增大，离子液体的位移也随之增大。研究了致动器在不同离子液体中的循环伏安响应和氧化还原开关动力学。
This paper reports the fabrication of a dry-type conducting polymer actuator using nitrile rubber (NBR) as the base material in a solid polymer electrolyte. The conducting polymer, poly( 3,4-ethylenedioxythiophene) (PEDOT), was synthesized on the surface of the NBR layer by using a chemical oxidation polymerization technique. Room-temperature ionic liquids (RTIL) based on imidazolium salts, e. g. 1-butyl-3-methyl imidazolium X ( where X =BF4-, PF6-, (CF3SO2)(2)N-), were absorbed into the composite film. The compatibility between the ionic liquids and the NBR polymer was confirmed by DMA. The effect of the anion size of the ionic liquids on the displacement of the actuator was examined. The displacement increased with increasing anion size of the ionic liquids. The cyclic voltammetry responses and the redox switching dynamics of the actuators were examined in different ionic liquids.
