An effective way to disperse metal nanoparticles without the risk of aggregation is to bond them covalently to a crosslinked network. In order to do this, nanoparticles must have reactive functionalities that can undergo a polymerization reaction. In this work, we show the synthesis of gold nanoparticles functionalized with OH groups (we shall denote them as OH-NPs). These OH-NPs were then reacted with 3-isocyanate propyl triethoxysilane (IPTES) in order to obtain triethoxysilane-functionalized gold nanoparticles (Si-NPs). Finally, Si-NPs were coreacted with a high functionality alkoxysilane to obtain a crosslinked network containing gold nanoparticles.
