摘 要: 为了提高Ag-IPMC的性能，采用两种不同的粗化方法对基膜进行粗化处理，同时对Ag-IPMC制备过程中的离子交换银氨溶液浓度及化学还原反应温度进行分析，并采用扫描电镜对3种影响因素下制备的Ag-IPMC样件表面形貌进行表征，分析其表面显微结构特性，最后对制备改善前后的Ag-IPMC样件进行致动性能对比分析。结果表明：采用自制的电动装置对基膜粗化处理效果较好，基膜表面凹坑均匀，且保证了其不被损伤；在Ag-IPMC制备过程中离子交换银氨溶液浓度为0.030 mol/L时最佳，这为后续还原反应中Ag单质沉积到基膜内一定深度提供良好的保障条件；化学还原反应温度为20℃时最佳，制备改善后得到的Ag-IPMC样件运动寿命比改善前的提高超过1倍，运动位移更加稳定。

Abstract:In order to improve the performance of the Ag-IPMC, two different coarsening methods were used to conduct coarsening processing for basement membrane. And the concentration of silver ion exchange ammonia solution and chemical reduction reaction temperature were studied during preparation process of Ag-IPMC. The surface morphology and microstructure of Ag-IPMC sample with three influence factors were analyzed using scanning electron microscopy. Drive performances of Ag-IPMC sample before and after preparation were compared and analyzed. The results show that the coarsening processing effect of basement membrane using self-made electric device is relatively excellent. Basement membrane surface has a even pit, and this also ensures its surface not to be damaged. Concentration of 0.03 mol/L of silver ion exchange ammonia solution is better in the preparation of Ag-IPMC, which provides a good condition for Ag substance deposition into basement membrane in subsequent reduction reaction. Additionally, it is most appropriate when chemical reduction reaction temperature keeps at 20 ℃. The motional lifetime of sample after preparation is increased by more than 100% and motional displacement is more stable.
