目前有相当大的兴趣开发机械化学材料，这些材料使用离子交换膜的膨胀技术，适合于建造非常小尺寸的机电致动器。全氟羧酸薄膜的两面都用化学方法镀上了金。聚合物带上的金电极之间的脉冲电压为2.0 V，使带在水中快速弯曲90度角，向带的阳极侧偏移8毫米。该复合材料的驱替性能是Nafion-Pt复合材料的5倍。本文详细介绍了采用全氟羧酸薄膜和金板复合材料制成的显著大弯曲运动聚合物微致动器。
There is considerable present interest in developing mechanochemical materials which use the swelling of ion exchange membranes technologies suitable for the construction of electromechanical actuators of very small dimensions. Both sides of a film of perfluorocarboxylic acid were chemically plated with gold. A pulse voltage of 2.0 V between the gold electrodes on the polymer ribbon gave a quick bend 90 degree angle, 8 mm displacement toward the anode side of the ribbon in water. The displacement performance of this composite is five times larger than that of Nafion-Pt composite. This report describes in detail the remarkably large bending motion polymer-micro-actuator using perfluorocarboxylic acid film and gold plate composite.
