Hence, the functionalization of GO with a silanecouplingagent significantly contributes to exploring the most optimal methods and conditions for preparing NR/GO nanocomposites through graft copolymerization. Despite this, research involving the hybrid filler GO/silica for grafting onto NR

route was demonstrated, and by selecting the type of silanecouplingagent the surface properties of the TiO2 nanoparticles could be tailored. This synthesis route has been further developed into a two-step synthesis to TiO2–SiO2 core–shell nanoparticles. Combustion of the silane coupling agents up to
700 °C leads to the formation of a nanometric amorphous SiO2 layer, preventing growth and phase transition of the in situ functionalized nanoparticles.
