▎ 摘　　要

The purpose of this paper is to investigate the effectiveness of anticorrosion layers based on graphene oxide (GO) nanosheets in solutions that simulate the composition of the pores in concrete contaminated with chloride ions. The corrosion-protective properties and surface characteristics of the coating layers improve significantly, due to the graphene adhered to the steel by van Der Waals force and chemical reduced reaction of GO synergistically, which were analyzed by the Fourier transform infrared spectroscopy, microscopy technique, contact angle measurements, potential-dynamic polarization and electrochemical impedance spectroscopy, etc. The reduced GO coating on steel surface possess the anticorrosion efficiency of 98.5% in concrete pore solution with 3 wt.% NaCl.
