针对水基离子聚合物金属复合材料(IPMC)在空气中性能不稳定且存在松弛变形这一问题
使用离子液体替代水作为IPMC内部溶剂
采用光固化材料对该材料进行表面封装
测试水基IPMC和离子液体型IPMC封装前后的驱动性能
对比水基IPMC和离子液体型IPMC在空气中的长期稳定性能。实验结果表明:在2 V电压驱动下
离子液体型IPMC的松弛变形消失
输出力和位移虽有所减小
但该类型IPMC可以承受高的驱动电压; 在8 V电压作用下
离子液体型IPMC封装后的材料变形为12 mm
输出力达到0.8 mN; 封装后的离子液体型IPMC的整体质量基本维持不变
驱动性能基本稳定
满足在空气中长期使用的要求。
T solve the problem that the applications of ionic polymer-metal composite are limited in the air due to relaxation effect and unstable performance in high humidity circumstance
ionic liquid is used to replace internal water as solvent
and the UV packaging technology is employed to maintain the stability of the structure. The deformation properties of water-based IPMC and ionic liquid-based IPMC are compared before and after packaging. Experimental results show that relaxation effects is eliminated when ionic liquid-based IPMC is driven by DC voltage. The material with ionic liquid type electrolyte layer can bear higher voltage to improve the drive performance
the displacement reaches to 12 mm
and the output force is 0.8 mN. The quality and the displacement of the structure after packaging keep unchanged and satisfy the service requirements in air.
