摘要

摘要: 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(0.2 mm、 0.4 mm、 0.8 mm)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0.3~0.8 Hz时试样具有最高的灵敏度, 其中0.8 mm试样在0.65 Hz 时的传感电压为17.82 mV, 灵敏度可达1030.06 mV/mm。

Abstract: Ion-exchange polymer metal composites with Ag as electrodes (Ag-IPMC) samples were manufactured by the chemical deposition method at the reaction temperature of 23℃ and 10℃. As shown from the morphologies of samples observed by SEM and EDAX, the samples manufactured at reaction temperature of 10℃ possess better electrode deposition effects than those manufactured at 23℃, and the thicknesses of surface and interlocked electrodes increase by 25% and 34%, respectively, and cracking and spalling on surface electrodes are suppressed. Sensing characteristics of samples with thickness of 0.2 mm, 0.4 mm and 0.8 mm at reaction temperature of 10℃ were tested and analyzed. The results indicate that samples voltage output and sensitivity obviously increase with increasing sample thickness. All samples are sensitive to low frequency excitation, especially within the range of 0.3-0.8 Hz. As the excitation frequency is 0.65 Hz, the sensing voltage and sensitivity of sample in thickness of 0.8 mm are 17.82 mV and 1030.06 mV/mm, respectively.
