Highly oxidation-resistant carbon-silicon-metal oxide hybrids derived from asilicon-containing polymer precursor

The silicon-containing thermosetting polymer, poly [(phenylsilylene) ethynylene-1, 3-phenyleneethynylene] (abbreviated as MSP), was hybridized with metal oxides, such as SiO2, TiO2, Al2O3 or B2O3 by a blending and sol-gel methods. Amorphous silicon containing carbon obtained by pyrolyzing MSP at 1000°C showed higher oxidation-resistance than the commercial amorphous carbon. The carbon-silicon-B2O3 hybrids (B2O3 8%) obtained by pyrolyzing the molding sample of MSP/B2O3 at 1000°C showed much higher oxidation-resistance than the carbon derived from MSP.
