| 英文摘要 | An interesting method for radiation cross-linking polycarbosilane (PCS) at high efficiency and low cost was developed by adding multifunctional monomers (trimethylolpropane trimethacrylate (TMPTMA) or divinylbenzene (DVB)). The effect of multifunctional monomers on the radiation cross-linking and ceramic yield of PCS was investigated. The results revealed that the addition of a small amount of multifunctional monomer can substantially improve the ceramic yield and reduce the absorbed dose by promoting cross-linking. The ceramic yields of radiation cross-linked PCS/2%DVB (300 kGy) and PCS/2%TMPTMA (300 kGy) were 74 wt% and 78 wt%, respectively, while that of the radiation cross-linked PCS (300 kGy) was only 64 wt%. The presence of double bonds in multifunctional monomers stimulated the combination reactions of free radicals in PCS induced by-ray irradiation and subsequently enhanced the efficiency of cross-linking. Furthermore, it was found that the incorporation of a small amount of multifunctional monomer hardly affected the chemical composition and crystallization behavior of the final SiC ceramics. |
