AbstractThermal reduced graphene oxide (TRGO) was incorporated into polyimide (PI) matrix as two-dimensional nanofillers and TRGO/PI nanocomposite anticorrosive coatings were fabricated. Then AC impedance spectroscopy and dynamic potential polarization curves were adopted to evaluate the electrochemical corrosion behavior of the obtained coatings in simulated seawater (3.5wt% NaCl solution). The results show that the addition of TRGO significantly improves the coating resistance and corrosion protection efficiency compared with pure PI coating. Besides, the TRGO/PI composite coating with the addition of 0.3wt% TRGO shows the most excellent anticorrosive property, with the maximum coating resistance of 1.3176×106Ω and the highest corrosion protection efficiency of 99.65%. The enhanced anticorrosive property can be attributed to the physical barrier properties of the TRGO with lamellar structure. © 2017, Science Press. All right reserved.
