Abstract
In the toluene solution of the precursor Polycarbosilane (PCS) containing low- molecular-mass additive Ti(OC 4 H 9 ) 4 , TiO 2 /SiC nanometer-scale functional compositional film with the surface TiO 2 layer on CF was formed in situ by means of polymer-derived precursors. The effects of Ti (OC 4 H 9 ) 4 concentrations and the maturating time were studied on the densification and TiO 2 particle size of surface layer. The compositions of film were TiO 2 and SiC crystal by XRD. According to the results of ESCA analysis, Ti(OC 4 H 9 ) 4 compound oozed gradiently from the pre-ceramic PCS to the surface layer after maturating time of 100 h. In the conditions of 45wt% Ti (OC 4 H 9 ) 4 and 100 h maturation, the nanometer-scale TiO 2 particles on continuous surface layer were formed by SEM photographs. The nanometer-scale TiO 2 /SiC functional compositional film can modify the resistance to oxidation of carbon fiber.
