| Abstract: | 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. |
