Thermally insulating polybenzoxazine aerogels based on 4,4′-diamino-diphenylmethane benzoxazine

Polybenzoxazine (PBO) aerogels were prepared from 4,4′-diamino-diphenylmethane (MDA) benzoxazine monomer by HCl-catalyzed ring-opening polymerization at room temperature after CO 2 supercritical drying. This study systematically analyzes the microstructures, thermal insulation properties, compressiv...
