Abstract

Functionalized graphene was firstly prepared by controllable chemical oxidation method, thus grafting reaction between graphene and triethylenetetramine could be realized. The results showed that the structure of graphene sheet is smoother after chemical modification. The properties such as compactness and adhesion of the epoxy resin coating were obviously improved due to the proper incorporation of the modified graphene. Chemical modification can also improve the graphene's dispersibility in and compatibility with epoxy resin binder, as a result, internal defects of the coating can be reduced, which makes the coating much compact and thus effectively prevents the inward migration of corrosive medium. In addition, chemically-bonded interfaces between the modified graphene and epoxy resin can be formed, which delays the destruction of the interface by alternating hydrostatic pressure, and thus prolongs the service life of the coating under this condition.

Key words: modified graphene organic coating alternating hydrostatic pressure failure mechanism
