Carborane is an outstanding raw material for high temperature resistant. POSS is an anti-atomic oxygen
compound. In this paper, the above-mentioned two materials are chemically combined by hydrosilylation. Two
kinds of polymers are synthesized and the thermal properties are evaluated by TGA in air. TGA results show that the
materials exhibit excellent high-temperature resistant properties. These materials could be used as coatings of hypervelocity
vehicles.
