摘要： 电致动高分子智能材料IPMC存在刚性小、输出位移较大、致动力小以及承受电压较低等缺点.因此,提出了利用导电树脂将多片IPMC粘结成多层n-IPMCs的改性方法.利用有限元方法分别建立了单片IPMC和双层并联微驱动器2-IPMCs的仿真模型,对其输出特性进行了仿真预测,继而利用导电树脂粘结技术制备了双层2-IPMCs样品,最后对该样品进行了性能测试实验.实验结果证明,基于导电树脂的2-IPMCs相对于单片的IPMC在输出力、输出位移、刚度、最大承受电压、性能持续性以及保水性等方面都有较大的改进.

Abstract: IPMC(ionic polymer metal composites) as a type of electro active polymer material has some disadvantages of low rigidity, non-desired output displacement, tiny actuating force and low withstanding voltage etc. A novel method was proposed to bond several pieces of IPMC strips together to form multi-layered n-IPMCs using conductive resin. Models of single- and multi-layered parallel connection IPMC micro-actuators were established based on finite element analysis method to predict their output characteristics. Double-layer IPMCs were then fabricated and characterized. The experimental results showed that the double-layer 2-IPMCs are significantly improved in aspects of output force, output displacement, stiffness, withstanding voltage and water retain property compared with that of the single-layer IPMC.
