摘　　要：离子聚合物复合材料IPMC(Ionic polymer-metal composite)是一种新型的电致动材料,在微小系统驱动方面有巨大的应用潜力,但输出力较低限制了该材料进一步的开发应用。本文采用聚合物溶液浇铸技术制备Nafion基底膜,通过化学镀方法在Nafion基底膜上均匀沉积铂金属电极,获得IPMC复合材料。针对IPMC输出力较低的缺点,通过多片薄膜并联设计的方法,提高IPMC驱动器的力输出性能。在IPMC测试平台上进行力输出性能测试,测试结果表明,多片IPMC叠加可显著提高IPMC的力输出性能,随叠加层数的增加,IPMC力输出叠加效率有所降低。Ionic polymer metal composites（!PMC）, a new kind of electro-active polymer, have great potential in micro systems actuators. However, IPMCs generate a small output force, which greatly limits their further appli- cations. In this paper, the Nation membranes were prepared by casting the liquid solution, and IPMCs were com- posed of the casted Nation membranes chemically surface-composited with a conductive medium such as platinum or gold by electroless plating. The blocking force was improved by multi-layerd IPMC membranes with parallel circuit. Then, the blocking force was measured by the apparatus for actuation tests. The results showed that multi- layers of IPMC membranes were apparently able to improve the force performance, and the efficiency decreased with the increasing number of layers.
