摘　　要：离子交换聚合物/金属复合材料(IPMC)可作为柔性的驱动器与传感器,用于仿生机械、医疗器械等领域。驱动器是IPMC的主要应用,存在输出功率低、驱动不稳定等问题。传感器是IPMC的重要应用,存在感应电压低、干扰大等缺陷。优化电极、电解质膜、电解质溶液的材料组成有望解决上述问题。驱动器方面,本文梳理了不同聚合物电解质膜的改性技术及驱动特点,重点归纳了电解质膜的成分、结构制约其物理性能(如离子交换当量、含水量、力学性能),进而制约其驱动性能(如位移、力输出)的规律。传感器方面,本文从电极形状、电解质膜结构、电解质离子尺寸3个方面,讨论了IPMC传感性能(如感应电压的幅值、稳定性)的优化技术。论文还展望了IPMC的未来发展方向。As flexible actuators and sensors,ion exchange polymer-metal composites(IPMCs)are widely used in bionic machinery,medical devices and other fields.Actuation is the main application of the IPMC,and IPMC actuators have bottlenecks such as low output power and unstable actuation.Sensing is another important application,and IPMC sensors endure some defects such as low induced voltage and large interference.For actuator,we discussed the modification techniques and driving characteristics of different polymer electrolytes,and focused on the structure-activity relationship of that,the compositions and structures the electrolytes determine their physical properties(e.g.,ion exchange capacity,water uptake,mechanical property),subsequently determine their electromechanical properties(e.g.,displacement,force outputs).For sensor,we discussed the optimization technologies of IPMC sensing properties(e.g.,amplitude and stability of the induced voltage)from three aspects of electrode shape,electrolyte membrane structure and electrolyte ion size.We also discussed IPMC's future research.
