摘　　要：采用溶胶凝胶工艺和电纺丝法制备了聚二甲基硅氧烷/二氧化硅(PDMS/SiO2)电纺纤维.纤维连续、直径均匀、表面光滑平整,形成了一块完整的纤维毡。并用场发射扫描电镜(FESEM)、红外光谱法(FT-IR)、热重分析法(TG)研究了纤维的形态、结构和热性能。结果表明,PDMS通过两端羟基与TEOS发生了缩合,电纺纤维具有良好的耐高温性能,并且随着PDMS含量的增加,纤维直径变粗。PDMS/SiO2 hybrid fibers were prepared by sol-gel technology and electrospinning methods. The fibers were smooth, continuous and were formed together into fiber mats. The morpholo- gies,components and thermal properties of the fibers were analyzed by FESEM, FT-IR, TG respectively. The results indicate that the condensation reaction occurres among hydroxyl group of polydimethylsiloxane（PDMS）and TEOS. The hybrid materials have excellent stability at high temperature and the fibers diameter increases with the increase of PDMS content.
