Syntheses of silsesquioxane (POSS)-based inorganic/organic hybrid and the application in reinforcement for an epoxy resin

► We have prepared a novel inorganic/organic hybrid material containing silsesquioxane and functional groups of epoxy. ► The hybrid material shows great reinforcement for crosslinked epoxy resin when mixed with the resin. ► The reinforcement is ascribed to nano-scale effect of the POSS structure and the anchor structure. ► Kinetics revealed that two kinds of curing reactions occurred in different temperature ranges.
