离子聚合物金属复合材料(ionic polymer metal composite)作为新型驱动材料在微小系统驱动等方面有着明确的应用前景,输出力较低和对水环境的依赖限制了该材料进一步的应用.本文采用正交实验设计法,针对IPMC制备过程中的3个主要参数,选用L16(45)正交表,以输出力为指标开展制备工艺的优化.结果表明主镀过程铂氨复合物的浓度对IPMC输出力的影响最大,Nafion膜中四乙氧基硅(TEOS)含量对输出力的影响次之,还原剂浓度对输出力没有显著影响.在实验确定的最优条件下,IPMC的最大输出力达到50mN,相应的最大位移为14mm.在最大输出位移性能相当的情况下,较常规条件最大力输出提高了2.4倍,有效工作寿命大幅提高,有效力输出延长了5.8倍,有效位移输出性能延长了5倍.该研究为IPMC进一步的应用奠定了坚实的基础.
As a new type of driving material, ionic polymer metal composite has a clear application prospect in the field of micro-system driving, etc. The low output force and the dependence on the water environment limit its further application.In this paper, Experimental design method, in order to IPMC preparation process of the three main parameters, the choice of L16 (45) orthogonal table, the output force as an indicator to carry out the preparation process optimization.The results show that the main plating process of platinum ammonia complex concentration of IPMC output force , The influence of TEOS content on Nafion membrane was the second, and reductant concentration had no significant effect on output power.Under the optimal conditions, the maximum output of IPMC reached 50mN , The corresponding maximum displacement of 14mm. In the case of the maximum output displacement performance, compared with conventional conditions, the maximum force output increased by 2.4 times the effective working life increased significantly, the effective output extended 5.8 times, the effective displacement output performance extended by 5 This study laid a solid foundation for the further application of IPMC.
