Abstract

Article history: With the purpose of preparing anticorrosive coatings, solvent-based epoxy resins often serve as raw Received 12 August 2015 material. Unfortunately, plentiful micro-pores are fabricated via solvent evaporation in the resin’ cur- Received in revised form 1 November 2015 ing process, which is an intrinsic shortcoming and it is thus necessary to obstacle their micro-pore for Accepted 7 November 2015 enhancing antiseptic property. To reduce the intrinsic defect and increase the corrosion resistance of Available online 14 November 2015 coating, we synthesize a series of SiO –GO hybrids through anchoring silica (SiO ) on graphene oxide 2 2 (GO) sheets with the help of 3-aminopropyltriethoxysilane and 3-glycidoxypropyltrimethoxysilane, and Keywords: disperse the hybrids into epoxy resin at a low weight fraction of 2%. Furthermore, we investigate the Graphene oxide appropriate preparation proportion of SiO –GO hybrids (namely: SiO –GO (1:5)). The electrochemical 2 2 Silica impedance spectroscopy (EIS) test and coatings’ morphology monitoring in corrosion process reveal that Epoxy coatings the anticorrosive performance of epoxy coatings is significantly enhanced by incorporation of SiO –GO Corrosion resistance 2 Sheet-like structure (1:5) hybrids to epoxy compared with neat epoxy and other nanofillers including SiO or GO at the same contents.
