▎ 摘 要
NOVELTY - Preparation of polystyrene-modified ceramic-based composite material involves preparing graphene-modified polycarbosilane solution using polycarbosilane solution and graphene suspension as raw materials, preparing fiber perform, impregnating graphene-modified polycarbosilane solution in fiber perform, and repeating the process for several times. USE - Preparation of polystyrene-modified ceramic-based composite material (claimed). ADVANTAGE - The method efficiently and economically provides polystyrene-modified ceramic-based composite material having excellent mechanical property, by simple method.
