For many practical applications, the most important factor is to have an improved interface between the matrix and dispersed phase in a compressible composite aerogel having a high degree of porosity and a large surface area. Although some measure of compressibility is obtained in polymer-based aerogels with a continuous backbone through the hybridization of the stiff backbone [polyvinyltrimethoxysilane (P-VTMS), −C–C−] and flexible backbone [poly(3-glycidyloxypropyl)trimethoxysilane (P-GPTMS), −C–O–C−], it seems that the extent of improvement is insignificant in terms of interface improvement, surface area increase, and ordered mesoporous network. In this study, the effects of the incorporation of graphene nanoplatelets (GnPs) on aerogels made of a backbone consisting of −C–O–C– (flexible backbone) were examined in terms of structural improvement and were compared with aerogels made of a …
