摘　　要：探索了离子聚合物金属复合材料(IPMC)的制备工艺,利用化学沉积的方法成功制备了铂型IPMC(Pt-IPMC)试样。采用SEM对试样表面电极形貌进行研究,对Pt-IPMC试样在4种波形激励信号(幅值2～4 V,频率0.06～0.14 Hz)下的致动位移进行了测试。结果表明:金属Pt在离子交换膜内部及外表面具有良好的沉积效果,内、外电极厚度均有不同程度的减小;随着激励信号幅值的增加,IPMC试样的变形能力增强,响应速度加快;在4种波形信号的激励下,试样均在频率为0.1 Hz时达到最大位移,且在方波信号驱动下具有最好的响应速度和变形量。The preparation technology of ion-exchange polymer metal composites（IPMC） was explored,and the Pt-IPMC samples were successfully prepared by a chemical deposition method.SEM was used for analyzing the topography and chemical composition of the surface electrodes.The displacement of Pt-IPMC sample was measured under four types of actuating signal（amplitude of 2～4V,frequency of 0.06～0.14Hz）.The results show that the Pt atoms deposit well both inside and outside of the exchange membrane so that the depths of interior and exterior electrodes decrease to some extent.It is also found that the deformability and response speed of the Pt-IPMC samples are improved with the amplitude of driving signal rising.Furthmore,the displacement of Pt-IPMC samples all reaches a peak for four types of signals,and the Pt-IPMC sample shows the best response speed and deformability under the square wave when the actuating frequency is 0.1Hz
