Excellent Anti-Corrosion Performance of Go and Mn Ions Double Modified Zn2sio4 Based Composite Material

Abstract

A composite material with excellent anti-corrosion performance was synthetized through organic-inorganic coordination chemical reaction, Manganese (Mn) ions and graphene oxide (GO) were dual inbuilt in Zn2SiO4, then the related structure and anti-corrosion performance was investigated. In this work, Mn-Zn2SiO4 silicate-based material was first prepared by Mn ions doping and its anti-corrosion protection properties were improved by 255.3% relative to blank epoxy resin coating. Subsequently, to further enhance the corrosion protection properties, GO/Mn-Zn2SiO4 composite materials was synthesized, and its corrosion protection properties were improved by 426.6% and 167.1% relative to blank epoxy resin coating and Mn-Zn2SiO4, respectively. GO/Mn-Zn2SiO4 material protected the metal substrate by photogenerating cathode effect, manganese ion magnetic induction effect, two-dimensional GO shielding effect, and cathode second protection effect synergistically. In summary, this work provided a new idea for the development of new anti-corrosion materials.
