Abstract
Structurally similar silicone ceramers were synthesized by sol–gel processing of organic silanes. The chemical structures of the hardened ceramer materials were investigated by studying the gaseous products produced during elevated temperature heating. Fourier transformation infra-red (FTIR) spectroscopy and thermogravimetric analysis (TGA) were utilized to study the degradation phenomenon in the ceramers. The pyrolyzed residues were analyzed by Raman and 29Si solid-state nuclear magnetic resonance (SSNMR) and X-ray diffraction (XRD) techniques. The surfaces of the residues were analyzed with a scanning electron microscope (SEM). The results from the characterization techniques were utilized to investigate the degradation mechanisms of the ceramer materials.
