摘　　要：采用1 H,1 H,2 H,2 H-全氟癸基三乙氧基硅烷对纳米二氧化硅进行表面修饰,然后通过机械共混法将改性纳米二氧化硅(F-SiO_(2))加入到有机硅橡胶中制备单电极F-SiO_(2)/硅橡胶基摩擦纳米发电机(FR-TENG),并考察了F-SiO_(2)含量对FR-TENG电输出性能的影响。结果表明,F-SiO_(2)的加入有效提高了FRTENG的电输出性能,其开路电压和短路电流都随着F-SiO_(2)用量的增加而呈现先增大后减小的趋势。当F-SiO_(2)质量分数为1.0%时,FR-TENG的输出性能最佳,短路电流达到最大值5.5μA,较纯有机硅橡胶摩擦纳米发电机提升了71%。FR-TENG接触分离产生的交流电可以通过整流桥转变为直流电,并可用于点亮33盏LED灯和计算器。Silicone rubber(SR)is one of the most important polymer materials with unique viscoelasticity and toughness.In this work,the surface of nano-silica was modified by 1 H,1 H,2 H,2 H-perfluorodecyltriethoxysilane to improve the dispersion of nano-silica in SR.Finally,the 1 H,1 H,2 H,2 H-perfluorodecyltriethoxysilane modified nano-silica(F-SiO_(2))/SR composites were used to fabricate a serial of F-SiO_(2)/SR based triboelectric nanogenerators(FR-TENG).
