摘　　要：离子聚合物金属复合材料(IPMC)是一种新型的电驱动软材料,具有质量轻、驱动电压低的优点,但也存在输出力较小、驱动时间短的缺点,限制了其应用前景。提出了一种在基膜内掺杂硅酸乙酯-氧化石墨烯(TEOS-GO)以提高保水性和驱动能力的银基IPMC,通过对纯Nafion IPMC与TEOS-GO/Nafion IPMC致动器的含水量、尖端位移、输出力和稳定性等参数的测试,证实优化后IPMC的驱动性能有明显的提升。实验结果表明,掺杂质量分数1.5%TEOS-GO的IPMC在3 V直流电压下,尖端位移达到16.579 mm,相当于纯Nafion IPMC的3.37倍;输出力最高达到0.439 gf(1 gf=9.8 mN),是纯Nafion IPMC的5倍。这种改进方式弥补了IPMC用于致动器的缺点,为今后的发展开拓了前景。Ionic polymer metal composite(IPMC)is a new kind of electric driven soft material,and has advantages such as light weight and low driving voltage.However,it also has limitations such as small output force and short driving time,which restrict its application prospects.A silver-based IPMC with ethyl silicate-graphene oxide(TEOS-GO)doped in the base film to improve water retention and driving capability was proposed.By measuring water content,tip displacement,output force and stability of pure Nafion IPMC and TEOS-GO/Nafion IPMC soft actuators,it is confirmed that the driving performance of the optimized IPMC has been significantly improved.The experimental results show that the tip displacement of IPMC doped with 1.5%mass fraction TEOS-GO reaches 16.579 mm at 3 V DC voltage,which is 3.37 times that of pure Nafion IPMC.The maximum output force reaches up to 0.439 gf(1gf=9.8 mN),which is 5 times that of pure Nafion IPMC.The optimization approach addresses the drawbacks of IPMC for actuators and opens up prospects for future development.
