• copolymerization of NR. Hence, the functionalization of GO with a silane coupling agent 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 silane coupling agent 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.

• , surface coverage, and hydrophobicity. Tuning the surface properties of the nanoparticles for different applications by selecting the silane coupling agent is discussed. We further report the effect of heat treatment of the nanoparticles for the formation of core–shell TiO2–SiO2 nanoparticles. Experimental
