| titleOfInvention | A kind of carborane modified ultra-branching poly carbon silane ceramics presoma and preparation method thereof |
| abstract | The invention discloses a kind of carborane modified ultra-branching poly carbon silane ceramics presomas and preparation method thereof.This method is using a kind of hyperbranched polycarbosilanes ceramic forerunner that Diels-Alder reaction can occur in the curing process, obtained carborane modified ultra-branching poly carbon silane ceramics presoma cured product densification bubble-free, carborane is introduced in the polymer, the cagelike structure of carborane can provide better heatproof oxidation performance energy to polymer, while the introducing of boron element is so that SiC/B after pyrolysis 4 C complex phase ceramic generates borosilicate compound under high temperature air environment, prevent the further oxidation of ceramic product, to improve the heatproof oxidation performance energy of ceramic product, and the low disadvantage of hyperbranched polycarbosilanes ceramic yield is improved, helps to realize hyperbranched polycarbosilanes preceramic materials in the extensive use in resistance to ablation field. |
