用化学沉积法制备银基IPMC(Ag-IPMC), 用扫描电镜和能谱分析仪研究其表面形貌和表面电极化学成分。 结果表明, Ag在离子交换膜内部和外表面的沉积效果良好; 对Ag-IPMC试件的直流驱动、不同状态下的含水特性以及拉力输出的测试结果表明, 低电压(小于1.6 V)刺激可使Ag--IPMC试件产生大变形, 其输出拉力可达自重的89倍。各项性能与激励电压的关系表明, Ag--IPMC的最佳直流激励电压为0.6--1.2 V。
Ag-IPMC was fabricated by using chemical deposition methods in this paper. The topography and chemical composition of the surface electrodes of Ag-IPMC were analyzed by scanning electron microscopy (SEM) and energy dispersive spectrum (EDS). And the DC-Actuating ability, moisture characteristic of different states and the performance of tensile output were tested. The results show that Ag deposits well both inside and outside of the exchange membrane. Ag-IPMC exhibits large deflection and significant tensile force for the stimulation of low voltage (less than 1.6 V). The relationship between various performance and excitation voltage shows that the best DC-excitation voltage for Ag--IPMC is 0.6--1.2 V.
