Green one-pot synthesis and processing of polyimide–silica hybrid materials

摘要: Inorganic–organic hybrid materials allow for combining features typical of the inorganic component with those organic in one material. Generally, preparation and compounds requires considerably different synthesis conditions. Hence, development one-pot routes to inorganic–organic is challenging. We herein report a fully green polyimide/silica (PI/SiO2) hybrids. Specifically, we co-condense both components hydrothermally, using nothing but respective precursors water. Furthermore, show that PI SiO2 can be covalently connected under hydrothermal conditions, compatibilizer (3-aminopropyl)-triethoxysilane. thoroughly investigate effect reaction including temperature, pH, precursor concentration time on morphology crystallinity final materials. The polyimide component, poly(hexamethylene pyromellitimide) was chosen its thermoplasticity, which allows processing PI/SiO2via sintering. For being solvent-free method, sintering qualifies as technique. This work first simultaneous condensation an
