摘要
本文在介绍离子聚合物金属复合材料(IPMC)作动机理的基础上,以一种镀Pt的IPMC材料为对象,通过实验方法研究了水分子对其作动性能的影响以及在直流和交流电压输入下的位移与内部电流特性,比较了不同输入波形以及不同输入电压幅值下的响应特征,并给出了这种IPMC的频率响应特性,从而为该材料的应用奠定了基础。
The electromechanical characteristics of ion polymer-metal composite （IPMC） with Pt as its electrodes is investigated. After the introduction of the working principle of electromechanical actuation, the effect of water molecular contained within IPMC was analyzed, and the internal current and displacement response of IPMC were measured under DC and AC voltage. Different driving waves form with several peak voltages were applied to the IPMC actuator, after which a comparison of response characteristics was studied and the best driven wave, frequency was offered, which might serve for the application in the future.
