Silica attached to graphene oxide surface with the load of homogeneous distribution is prepared.
Silica is anchored on graphene oxide sheets which benefits from synergistic effect of APTS and GPTS.
The SiO2–GO (1:5) sheet hybrids have fine dispersion in the epoxy resin.
The incorporation of SiO2–GO hybrids significantly enhances corrosion resistance of epoxy coatings.
