Abstract:A tough hybrid hydrogel has been developed by dual in situ sol–gel reaction of γ‐ethacryloxypropyltrimethoxysilane (MPTMS) and tetrabutyl titanate, as well as in situ radical polymerization of acrylamide (AM) and MPTMS. In this hydrogel, covalently bonded SiO2 and TiO2 nanoparticles were used as inorganic filler and multifunctional crosslinker. Nano‐TiO2 was bonded onto the surface of SiO2 by forming TiOSi bonds and SiO2 bonded with polymer chains by the formation of COSi bonds, which were confirmed by Fou… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
