Abstract

Silicon oxycarbides (SiOxCy) fabricated at $1300^{\circ}C$ from iodine-doped polycarbosilane (PCS) have been shown to have high tensile strength. Iodine doping of PCS can induce oxygen atoms into the molecular structure of PCS, which forces it to start cross-linking at a relatively low temperature of $180^{\circ}C$. The mechanical properties of fabricated SiC fibers strongly depend on the degree of cross-linking during stabilization. In this study, the role of oxygen in the cross-linking reaction of PCS was investigated by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TG), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS) analysis.
