Graphene oxide used as the modifier to prepare silica-encapsulated waterborne flaky aluminium for enhanced anticorrosive property
[摘要] Silica-encapsulated waterborne flaky aluminium (SEWFA) is widely used in industrial fields, but its corrosion hampers its long-term use. Herein, a sol–gel method was used to prepare graphene oxide (GO)-modified SEWFA (GO-SEWFA). The oxygen-containing functional groups of GO can react with tetraethyl orthosilicate to form a well-dispersed silica/GO matrix on the surface of GO-SEWFA. The hydrogen evolution results demonstrated that GO covalent bonding, combined with silica encapsulation on the surface of flaky aluminium, could effectively improve the anticorrosive performance.
