Synthesis and characterization of polymer-derived SiCN aerogels are reported. The wet pre-ceramic gels are synthesized via hydrosilylation reaction of a polysilazane with divinylbenzene as cross-linker using cyclohexane as solvent. Subsequently, the wet polymeric gels are dried using supercritical carbon dioxide for the removal of the solvent. The SiCN ceramic aerogels are obtained through pyrolysis...
