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 process of the ionic polymer metal composite (IPMC) was explored. The platinum IPMC (Pt-IPMC) sample was successfully prepared by chemical deposition. The morphology of the electrode on the surface of the sample was investigated by SEM. The displacement of the Pt-IPMC sample under four kinds of waveform excitation signals (amplitude 2 ~ 4 V, frequency 0.06 ~ 0.14 Hz) was tested. The results show that the metal Pt has good deposition effect on the inner and outer surfaces of the ion exchange membrane, and the thickness of the inner and outer electrodes decreases to some extent. With the increase of the amplitude of the excitation signal, the deformability of the IPMC sample increases. The response Under the excitation of four kinds of waveform signals, the samples reach the maximum displacement at the frequency of 0.1 Hz and have the best response speed and deformation under the driving of the square wave signal.
