Abstract:

利用化学沉积的方法,在反应温度为23℃和10℃的条件下,制备银型离子聚合物金属复合材料(Ag-IPMC)。SEM和EDAX观测结果表明:反应温度10℃下制备的试样与23℃的试样相比,具有更好的电极沉积效果,其内、外电极厚度分别增加25%和34%,且外电极的开裂和剥落现象得到抑制。对10℃条件下制备的三种不同厚度的试样(0.2mm、0.4mm、0.8mm)的传感特性研究表明:随着厚度的增加,试样输出电压和灵敏度增强趋势明显;三种试样均对低频激励敏感,在0.3~0.8Hz时试样具有最高的灵敏度,其中0.8mm试样在0.65Hz时的传感电压为17.82mV,灵敏度可达1030.06mV/mm。
