摘要：
In this study, the hyperbranched polyester (HBP) was grafted onto the surface of graphene oxide (GO) to prepare functionalised GO (fGO). Results of X-ray photoelectron spectra, Thermogravimetric analysis, Fourier transform infrared spectroscopy and Transmission Electron Microscopy confirmed the success of grafting. Moreover, the anti-corrosion performance and barrier properties of the bare steel, and steel with epoxy (EP) coating, steel coated with EP/GO and EP/fGO were comparatively studied. It was found that EP/fGO showed enhanced anti-corrosion capability and barrier properties to H2O and O(2)compared with EP/GO, attributed to the surface modification of GO by HBP. Moreover, the role of surface modification using HBP on the performance of EP/GO composite coating was also discussed, related mechanism was proposed.
