【摘要】：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2V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12mm,输出力达到0.8mN;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。
[Abstract]:In order to solve the problem that the properties of aqueous ionic polymer metal composites (IPMC) are unstable in air and there is relaxation deformation, the ionic liquid is used to replace water as the internal solvent of IPMC. The surface encapsulation of the material was carried out by using light-cured material, and the driving performance of water-based IPMC and ionic liquid IPMC was tested before and after encapsulation. Compared with the long-term stability of water based IPMC and ionic liquid IPMC in air, the experimental results show that the relaxation deformation of ionic liquid type IPMC disappears under 2V voltage. The output force and displacement are reduced, but this type of IPMC can withstand high driving voltage. Under the influence of 8 V voltage, the material of IPMC encapsulated with ionic liquid was deformed to 12mm and the output force reached 0.8mN. The whole quality of the encapsulated ionic liquid IPMC remains basically unchanged, and the driving performance is basically stable, which can meet the requirements of long-term use in air.
