High Mass Residual Silica/Polybenzoxazine Nanoporous Aerogels for High-Temperature Thermal Protection
Lanfang Liu,

Abstract:High-performance
thermal protection materials are urgently
needed
for thermal protection applications under extreme conditions. Organic
aerogels are considered to be promising and efficient thermal protection
materials, but their low mass residuals have been the main obstacles
to limiting their development and application. Herein, by an in situ
copolymerization of benzoxazine prepolymers and N,N-dimethylformamide (DMF)-soluble silica (SiO2) precursors, polybenzoxazine (PBO) with increased SiO2 contents was for… Show more
