The effect of etching temperature on the compositional and structural evolution of ceramer from polysiloxane in chlorine
Source abstract
Abstract
Abstract In this paper, we used a novel carbide (or ceramer) as the carbon precursor and studied the effect of etching temperature on its compositional and structural evolution in chlorine condition. The ceramer produced from a commercially available polymethyl(phenyl) siloxane resin at 600 °C under nitrogen still includes some organic groups (e.g., Si H, Si CH3, Si Ar), which cannot survive in chlorine for 3 h in range of 450–900 °C. The ceramer can be completely converted to carbon while the etching temperature exceeds 600 °C. Higher ordering at elevated etching temperatures and apparent increasing of mesopores at 600 °C were observed.
