英文摘要Graphene with shielding effect can improve the corrosion resistance of organic coatings, but its high electrical conductivity intensifies the corrosion of metal substrate due to micro-galvanic effect on the interface of coating and substrate. The regulation of graphene's conductivity can inhibit the corrosion-promotion effect. Hence, graphene supported attapulgite (GNS-ATP) nanosheets with lower conductivity were successfully prepared by using TEOS as coupling agent, then were introduced into Sol-gel coatings via using gamma methacryloxypropyltrimethoxysilane (MPS) and tetraethyl orthosilicate (TEOS) as precursors. The characterization on corrosion resistance of the hybrid coatings illustrates that a small amount of well-dispersed GNS-ATP nanosheets can significantly enhance the corrosion resistance, mainly depending on the structure and performance characteristics of GNS-ATP nanosheets. Such advantages on reducing porosity and conductivity of hybrid coatings offer a better corrosion resistance.
