As a new type of flexible smart material, ionic polymer-metal composite (IPMC) has the advantages of being lightweight and having fast responses, good flexibility, and large deformation ranges. However, IPMC has the disadvantages of a small driving force and short lifespan. Based on this, this paper firstly analyzes the driving mechanism of IPMC. Then, it focuses on the current preparation technology of IPMC from the aspects of electroless plating and mechanical plating. The advantages and disadvantages of various preparation methods are analyzed. Due to the special driving mechanism of IPMC, there is a problem of short non-aqueous working time. Therefore, the modification research of IPMC is reviewed from the aspects of the basement membrane, working medium, and electrode materials. Finally, the current challenges and future development prospects of IPMC are discussed.
作为一种新型的柔性智能材料，离子聚合物-金属复合材料（IPMC）具有重量轻、响应速度快、柔韧性好、变形范围大等优点。然而，IPMC 也存在驱动力小、寿命短的缺点。基于此，本文首先分析了 IPMC 的驱动机制。然后，从化学镀和机械镀两个方面重点介绍了目前 IPMC 的制备技术。分析了各种制备方法的优缺点。由于 IPMC 的特殊驱动机制，存在非水工作时间短的问题。因此，从基底膜、工作介质和电极材料等方面综述了 IPMC 的改性研究。最后，讨论了 IPMC 当前面临的挑战和未来的发展前景。
