Abstract

Highly temperature stable mesoporous materials have excellent properties and potential applications. Here we show a novel poly(vinyl)silazane-block-polystyrene diblock copolymer, which was synthesized by controlled/living free radical polymerization with reversible addition fragmentation chain transfer (RAFT) route. The obtained diblock copolymer occurs the phaseseparation on the nanoscale to form ordered nanostructure, which is converted to mesoprorous ceramic after heating at 800oC. This route demonstrates the preparation of highly temperature stable mesoporous silicon carbon nitrides (SiCN) ceramic film directed from highly cross-linking poly(vinyl)silazane blocks with high ceramic yield, which is different from previous pathway.
