Abstract
In this paper, isophorone diisocyanate is used to modified with graphene oxide, in which the isocyanate group can react with the oxygen-containing functional group in the graphene oxide. Then we can obtain the modified graphene oxide, thereby allowing the occurrence of grafting reaction on the graphene oxide and the polyurethane resin. Scanning electron microscopy, Fourier transform infrared spectroscopy, neutral salt spray test and electrochemical test are used to characterize the structure and properties of the modified graphene oxide and polyurethane coatings.
