Abstract
The use of coatings of functionalized nanostructured carbon based composite to inhibit corrosion is an area getting much of attention among scientists and industrialists. Lately, Graphene has started to play an important role in many applications. Graphene possesses excellent mechanical and thermal stability, low chemical reactivity, impermeability to most of gases, and high transparency. Thanks to these properties, Graphene is so far finding some applications for protective coatings. However, Graphene is apolar and nanostructured, so that is difficult to be dispersed into polar polymers as epoxy resin. In this paper, results of using chemically modified Graphene to reinforce the physico-mechanical properties and corrosive resistance properties of the epoxy paint coating are presented. Graphene was modified by oxidative method with mixtures of H2SO4, H3PO4 and KmnO4 solutions. The properties of obtained products were characterized by somephysico-chemical methods such as Fourier transformed Infrared Spectroscopy (FTIR), X-ray diffraction (XRD). The physico-mechanical and anti-corrosion properties of paints based on chemically modified Graphene-epoxy nanocomposite have been exceptionally superior to that of paints based on epoxy and Graphene.
