在不同的沉积温度-修饰温度(25℃-25℃,15℃-25℃,15℃-15℃,10℃-10℃,7.5℃-15℃,7.5℃-7.5℃)设定下,以化学沉积的方法制备银型离子聚合物金属复合材料(Ag—IPMC),并对制得试样进行了表面形貌观察以及拉伸测试和动态位移测试。结果表明:制备温度在7.5~25℃范围内,反应温度越低,离子交换膜表面所沉积的银粒子团聚颗粒越细小。在7.5℃-7.5℃下制备试样比25℃-25℃下制备的试样团聚颗粒直径小60%。电极厚度受温度影响较大,不同温度下内、外层电极厚度差异明显(内:~130%,外:~70%);制备温度在15℃-15℃的试样具有最大的弹性模量(比最小值大28%)。在实验温度范围内,最大驱动变形量随着反应温度的降低而增大,其最大值比最小值大80%。
Ion- exchange polymer metal composites with silver as electrodes (Ag - IPMC) samples were manufactured by the chemical deposition method under different deposition temperatures and modification temperatures of 25 ℃-25 ℃, 15 ℃-25 ℃, 15 ℃- 15 ℃, 10 ℃-10 ℃, 7.5 ℃-15 ℃ and 7.5 ℃-7.5 ℃. The topographies of chemical composition of the surface electrodes were analyzed. The tensile experiments and dynamic displacement tests of Ag - IPMC samples were taken. The results show that the diameters of Ag aggregations outside of the exchange membrane are smaller under lower temperature among the manufacturing temperature range of 7. 5 ℃ to 25 ℃. Comparing the samples manufactured at reaction temperature of 7. 5 ℃ - 7. 5 ℃ to those manufactured at 25 ℃- 25 ℃, the diameters of Ag particles are decreased by 60~. Electrode thickness of Ag - IPMC is affected deeply by temperature, the thicknesses of the surface and interlocked electrodes differ obviously (interlocked: ~ 130 %, surface: ~ 70 ~). The sample with the maximum elastic modulus is prepared under 15 ℃ 15 ℃, 28~ larger than the minimum value. Within the experimental temperature range, the maximum driven deformation increases as the reaction temperature being lower, and the maximum value is 80~ larger than the minimum.
