And the synthesized product (Mg(OH)2 nanorods/GO, MG) is further functionalized with ethylenediamine (FMG) and finally dispersed in a specific proportion in the epoxy resin primer. It was coated on the test steel plate from Q-PANEL, and the corrosion resistance effect was verified by Tafel curve. From the results, when the doping amount of FMG30 and 50 increased to 2 wt%, the corrosion rate decreased sharply from 1.4*10-2 mm/year of undoped FMG to 9.77*10-4 and 8.96*10-4 mm/year, and the corrosion rate of FMG10 reached 1.14*10-3 mm/year when the doping amount reached 2 wt%. From the conclusion, the doping of the FMG series can effectively improve the corrosion resistance.
