摘 要: 為了提高Ag-IPMC的性能，采用兩種不同的粗化方法對(duì)基膜進(jìn)行粗化處理，同時(shí)對(duì)Ag-IPMC制備過(guò)程中的離子交換銀氨溶液濃度及化學(xué)還原反應(yīng)溫度進(jìn)行分析，并采用掃描電鏡對(duì)3種影響因素下制備的Ag-IPMC樣件表面形貌進(jìn)行表征，分析其表面顯微結(jié)構(gòu)特性，最后對(duì)制備改善前后的Ag-IPMC樣件進(jìn)行致動(dòng)性能對(duì)比分析。結(jié)果表明：采用自制的電動(dòng)裝置對(duì)基膜粗化處理效果較好，基膜表面凹坑均勻，且保證了其不被損傷；在Ag-IPMC制備過(guò)程中離子交換銀氨溶液濃度為0.030 mol/L時(shí)最佳，這為后續(xù)還原反應(yīng)中Ag單質(zhì)沉積到基膜內(nèi)一定深度提供良好的保障條件；化學(xué)還原反應(yīng)溫度為20℃時(shí)最佳，制備改善后得到的Ag-IPMC樣件運(yùn)動(dòng)壽命比改善前的提高超過(guò)1倍，運(yùn)動(dòng)位移更加穩(wěn)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.
