Polysiloxane-diamine modified gel as precursor to crystalline/amorphous Si3N4

New hybrid organic-inorganic materials are prepared by reaction of polymethylhydrosiloxane (PMHS) with aniline (An) or 4,4′-diamino,diphenyl methane (APM) through a condensation between NH2-terminated amines and Si—H groups. The obtained modified-polysiloxane is a liquid polymer (PS-An) in the first...
