摘　　要：研究了IPMC的制备过程.制备主要分为前期预处理、主化学镀反应和次化学镀反应.在进行一次主化学镀反应之后,对比了不同次数的次化学镀反应所制备的样品的性能.设计了用于驱动IPMC的信号发生器,建立了基于PC机和数据采集卡的测试平台.对制备出来的样品进行了致动特性的测试,测试了激励信号的频率、幅值、以及镀膜厚度对致动特性的影响,为人工肌肉的控制设计提供了依据.实验结果表明:镀膜的电阻和激励信号的频率越小,摆动幅度越大;激励信号的幅值越大,摆动幅度越大;镀层厚度增大有利于电阻的降低,但是由于表面硬度的增加,镀膜并不能太厚;镀膜的打磨导致了电极的不均匀,增大了电阻,降低了材料活性.The preparation process of ionic polymer-metal composite（IPMC） as artificial muscle includes three steps： the pre-treatment, and the primary and secondary chemical plating reactions. Properties of the specimens to which the number of secondary chemical plating reactions were done differently after primary ones were in contrast with each other. With a signal generator designed to actuate IPMC, a test platform based on PC and data acquisition card was built to test the actuating characteristic of prepared specimens and the influence of frequency and amplitude of exciting signal and plating thickness on the characteristic so as to provide reterence for the design and control of IPMC. Testing results showed that the lower the resistance of IPMC plating and the frequency of exciting signal, the higher the voltage of exciting signal, the bigger the fluctuation range. Increasing the plating thickness will facilitate the decrease in IPMC＇ s resistance, but the plating cannot be too thick because of the increasing hardness. Burnishing the plating will result in inhomogeneous electrode surface, thus increasing the resistance of IPMC and decreasing its activity.
