英文摘要：

Ionic polymer-metal composites（IPMC） have attracted much attention in the field of bio-mimic due to their soft actuation. The actuation mechanism, the structure and the preparation of basic IPMC membrane and the fabrication of electrodes of IPMC are discussed. The basic materials of IPMC are classified according to the molecular structure of membrane. Based on the chemical structure of the basic membrane, the relationship between the structure and the properties is discussed, including the ion exchange capacity, the swelling property, absorption property, the blocking force and the deformation behavior. Also, the procedure of making electrodes is summarized. At last, the methods to improve the actuation properties are reviewed and discussed.
