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%。
Under the different deposition temperature-modification temperature (25 ℃ -25 ℃, 15 ℃ -25 ℃, 15 ℃ -15 ℃, 10 ℃ -10 ℃, 7.5 ℃ -15 ℃, 7.5 ℃ -7.5 ℃) (Ag-IPMC) was prepared by chemical deposition. The surface morphology, tensile test and dynamic displacement test of the prepared samples were also investigated. The results show that the smaller the reaction temperature is, the finer the silver particles deposited on the surface of the ion exchange membrane are at the preparation temperature of 7.5 ~ 25 ℃. Samples prepared at 7.5 ° C - 7.5 ° C have a 60% smaller diameter than agglomerated particles prepared at 25 ° C - 25 ° C. The electrode thickness is greatly influenced by the temperature. The difference of the thickness of the outer electrode and the outer electrode is obvious at different temperatures (~130%, outer: ~ 70%). The samples prepared at 15 ℃ -15 ℃ have the highest elastic modulus (28% greater than the minimum). In the experimental temperature range, the maximum driving deformation increases with the decrease of the reaction temperature, the maximum value is more than 80% of the minimum value.
