▎ 摘　　要

This work is ultimately aimed to deposit graphene oxide (GO) nanosheets onto the surface of copper (Cu) pipe by electrophoretic deposition (EPD) technique for enhancing the corrosion resistance. A stable aqueous GO suspension was prepared by liquid exfoliation of graphite oxide in deionized water which acted as an EPD electrolyte solution. Anodic deposition on Cu pipe was carried out under different operating parameters such as applied voltage, running time and GO nanosheets concentration. The GO-deposited film onto Cu pipe was investigated using scanning electron microscope, X-ray diffraction and Fourier transform infrared spectroscopy. The results showed that 20V and 60s deposition time with 0.5mg/ml concentration induced a uniform continuous coating film on Cu pipe. The corrosion resistance of Cu pipe treated with GO which was tested in 3.5% sodium chloride corrosive media was twofold higher than that of untreated Cu pipe. Collectively, the Cu pipe treated with GO using EPD deposition technique would have a potential in the application of harsh corrosive industrial environments.
