本研究制备了一种干式导电聚合物作动器。以含1-丁基-3-甲基咪唑双（三氟甲基磺酰基）亚胺（BMITFSI）离子液体的丁腈橡胶（NBR）作为固体聚合物电解质，具有较高的离子电导率和电稳定性。丙烯腈（ACN）含量为23,35和40 mol%的不同等级的nbr与BMITFSI具有良好的相容性。采用动态力学分析和阻抗分析对固体聚合物电解质的热力学性能和离子电导率进行了表征。在含有40 mol% ACN的NBR样品中，在BMITFSI中活化的NBR样品在20℃时的最大电导率为2.54 × 10(-4) S cm（-1）。采用化学氧化聚合的方法，在固体聚合物电解质表面合成了导电聚合物聚（3,4-乙烯二氧噻吩）（PEDOT），得到固体聚合物作动器结构。考察了丁腈橡胶组成对驱动性能的影响。(c) 2007 Elsevier B.V.版权所有
In this study, a dry type conducting polymer actuator was prepared. Nitrile rubber (NBR) containing ionic liquid, 1-butyl-3-methyl imidazolium bis(trifluoromethyl sulfonyl)imide (BMITFSI), was utilized as the solid polymer electrolyte exhibiting high ionic conductivity as well as electrical stability. Various grades of NBRs having different amounts of acrylonitrile (ACN), viz. 23, 35 and 40 mol%, were found to be well compatible with BMITFSI. The thermomechanical property and ionic conductivity of the solid polymer electrolyte were characterized by dynamic mechanical analysis and impedance analysis, respectively. A maximum conductivity of 2.54 x 10(-4) S cm(-1) at 20 degrees C was achieved in the NBR sample containing 40 mol% ACN activated in BMITFSI. A conducting polymer, poly(3,4-ethylenedioxythiophene) (PEDOT), was synthesized on the surface of the solid polymer electrolyte by chemical oxidative polymerization to yield the structure of solid polymer actuator. The effect of the NBR composition on the actuation behavior was examined. (c) 2007 Elsevier B.V. All rights reserved.
