摘　　要：以离子聚合物金属复合材料(IPMC)作为驱动器,应用于新型仿变形虫机器人运动中,为满足运动系统参数要求,研究了IPMC智能材料的结构、弹性模量与加电变形性能。实验制备了IPMC材料,采用SEM对其表面及断层电极金属形貌进行表征,纳米压痕仪测量其硬度及弹性模量,对加电形变性能采用跟踪记录材料变形过程,并运用图像处理,展示了IPMC材料变形与加电时间、电压之间的关系。结果显示,本文制备了具有均匀致密表面电极的IPMC材料,其硬度为0.0349GPa,弹性模量为1.8935Gpa,在低电压(2V)时,随时间增加,材料形变量增加较为平缓,高电压(6V)时,材料具有较快的响应变形的时间,并在达到最大变形量后有回复变形的趋势。Ionic exchange polymer metal composites（IPMC） as the actuator,is used in the movement of novel imitation amoeba robot.In order to meet motion system parameter,the structure of IPMC intelligent material,elastic modulus and power-distortion performance was studied.Preparation of IPMC,its surface and fault morphology of metal electrodes were characterized by SEM.The material hardness and elastic modulus were measured by nano-performance instrument.To characterize power-distortion,material deformation process was track recorded,Using image processing,the relationship between deformation of IPMC and power-up time and voltage was exposed.The result,shows that the surface electrodes with a uniform density of IPMC material can be obtained.Its hardness is 0.0349GPa and elastic modulus is 1.8935GPa.Under the low-voltage（2V）,material shape variable flatly increases,as the time increases,under high-voltage（6V）,the response time of deformation fast.And after the maximum deformation,deformation value starts with drawing.
