摘要

以具有典型工艺特征的金型和钯型离子聚合物金属复合材料(Au-IPMC 和Pd-IPMC)为研究对象

旨在阐释不同工艺过程和电极制备的IPMC材料随含水量变化其机电性能存在差异的现象。测量了两种IPMC材料静态含水量和环境湿度之间的关系

探讨了材料在湿态和干态下与室温湿度交换平衡过程中含水量的动态变化规律

测试了不同含水量下IPMC材料的力电响应关系

并将其转换为不同的湿度环境下的响应关系。实验结果表明:两种电极的IPMC材料在不同的湿度条件下含水量及变形规律具有相似性

即高含水量下呈现松弛变形

低含水量下无松弛变形; 与Pd-IPMC材料相比

不同湿度条件下对应的Au-IPMC含水量相对偏低

且在95%稳态湿度下

Au-IPMC材料具有更好的驱动性能

变形达到17.4 mm。

Abstract

To clarify the performance difference dependent on the water content of IPMCs with different fabrication process and electrodes

the relation between the static water content and steady-state humidity is determined firstly

and the dynamic change processes of water content then are tested by exchanging equilibrium with room temperature humidity in full wet state and full dry state respectively. The electro-mechanical response of Au-and Pd-based IPMC materials with different water content is characterized and converted to the response under different humidity environment. The experiments show that both deformation processes get similar with different water content and humidity

and the relaxation deformation appears for high water content and disappears for low water content. The water content of Au-IPMC is lower with different humidity than Pd-IPMC

and under RH 95%

Au-IPMC has better driving performance with deformation up to 17.4 mm.
