主要研究钯电极型离子聚合物-金属复合材料(Pd-ionic polymer-metal composite,Pd-IPMC)的制备工艺.以增加 Pd-IPMC 的电致动位移为优化目标,采用正交优化方法,针对浸泡还原镀和化学镀两个核心步骤进行了参数优化,探索了主要工艺参数对材料电致位移的影响规律.实验结果给出了工艺参数的优化值,以及这些参数对材料性能的影响水平和效应曲线.由优化后工艺参数制备的 Pd-IPMC 性能较优化前有显著提高,且优于 ERI 公司商业化的 IPMC.研究结果充分验证了 Pd 作为 IPMC 电极的可行性,解决了现有 Pd-IPMC 材料致动性能不理想的难题,对于制备低成本、大变形的 IPMC 材料,并促进其工程应用具有重要意义.
This paper mainly focused on the manufacturing process for Pd-IPMC.In order to improve the electro-active displacement of Pd-IPMC,the main parameters in the two core steps,the impregnation-reduction plating (IRP)and the autocatalytic plating (ACP),were optimized with an orthogonal array method.Furthermore,the influences of these parameters on the final displacement were analyzed and the optimized value,effect ranges and effect curve for the manufacturing parameters were presented.In addition,Pd-IPMC manufactured with the optimized parameters showed significant improvement in the displacement and exhibits better performance than the Pt-IPMC and Pd-IPMC purchased from ERI.This research verified the feasibility of using Pd as electrode for IPMC and greatly improved the unsatisfied performance of current Pd-IPMC;therefore,it will be of great significance for guiding the manufacture of low-cost,large-displacement IPMC materials and will promote their industrial application.
