Abstract

We report the synthesis of silicon oxycarbonitride ceramic-graphene oxide (SiCNO–GO) composites by using polyvinylsilazne (PVSZ) and GO as precursors through cross-linking processes, in which GO organizes into microspheres in the SiCNO matrix. The formation of GO microspheres significantly enhances the electrical conductivity of SiCNO. The electrical resistivity of SiCNO–GO composites shows a negative temperature coefficient in the range from 25°C to 600°C. We demonstrate the application of SiCNO–GO composites as the functional component of high-temperature sensors.
