摘　　要：将粒径分布均匀的纳米Fe3O4颗粒、甲基三甲氧基硅烷均匀分散在由十二烷基苯磺酸钠在水中形成的微胶束中,在酸催化条件下,甲基三甲氧基硅烷在纳米Fe3O4颗粒表面发生水解缩合,制备了包覆均匀的纳米SiO2/Fe3O4磁流体。通过二步法在涤棉织物表面沉积纳米磁性颗粒与聚苯胺导电聚合物的复合膜以制备有机无机复合膜导电织物,与聚苯胺单层膜导电织物相比,该有机无机复合膜导电织物具有更低的电阻率,且电阻率随着纳米磁性颗粒含量的增加呈现减小趋势。Fe3O4 nanoparticles with uniform size and methyltrimethoxysilane（MTMOS） were evenly dispersed in the sodium dodecyl benzenesulfonate（SDBS）/water micelle.In the presence of hydrochloric acid nano-scale SiO2/Fe3O4 magnetic fluid were prepared by hydrolysis and polycondensation of MTMOS on the surface of Fe3O4 nanoparticles.Conductive T/C fabric with organic-inorganic composite films was prepared through depositing on its surface polyaniline and nano-magnetic particles by two-step method.It had lower resistivity when compared with conductive T/C fabric with polyaniline-based single-layer film,and its resistivity decreased with the increase of added amount of nano-magnetic particles.
