Abstract

Polycarbosilane was synthesized from polydimethylsilane in the presence of ZSM-5 (Si/Al=30) as a catalyst at 350°C. Characterization of synthesized polycarbosilane was performed with ²⁹Si Solid NMR, FT-IR, TG, and GPC analysis. The number average molecular weight (M _n) of the polycarbosilane was 2,430. A continuous pcs fiber was fabricated by melt spinning this precursor under an inert atmosphere. Fibers dispersed with nano-sized SiC crystallites were obtained by the pyrolysis of thermally cured pcs fiber at 1200°C for 1 h under Ar atmosphere.
