摘要
以Ｔｉ（ＯＢｕ）４与低分子量聚硅烷为原料合成不同含钛量的聚钛碳硅烷，经熔融纺丝、空气不熔化及高温烧结等工艺，制备出了电阻率为１０６～１０３Ω·ｃｍ的Ｓｉ－Ｔｉ－Ｃ－Ｏ纤维。通过ＩＲ、ＧＰＣ、ＶＰＯ、ＸＰＳ等分析手段，系统地研究了钛含量对纤维的制备。
Polytitanocarbosilanes(PTC) with different Ti contents were synthesized by liquid polysilane(LPS) and Ti(OBu) 4, Through melt spinning, air curing and heat treatment, the Si Ti C O fibers with good mechanical and electric properties were prepared. The effects of Ti on the preparation, structure and electric properties of these Si Ti C O fibers were systematically studied by IR, GPC, VPO and XPS.
