Abstract
Corrosion is ubiquitous in life. In order to further improve anti-corrosion of nano-Ti polymer coatings of our previous research, graphene slurry is filled to modify nano-Ti epoxy resin coatings. Structure, anti-permeability, anti-corrosion and anti-wear properties of Nano-Ti polymer functional coatings with different graphene slurry have been investigated systemically by field emission scanning microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), immersion test, electrochemical measurements and wear test. FE-SEM results showed graphene can disperse well in nano-Ti polymer coating when the content of graphene is 0.5 wt%. Moreover, the results showed that added graphene can enhance the anti-permeability, anti-corrosion, and anti-wear properties of nano-Ti polymer coatings. Nano-Ti polymer/graphene functional coatings showed optimal comprehensive performance and anti-corrosion performance as the graphene content was 0.5 wt%. The diffusion coefficient is 0.44×10− 14 m2·s− 1, the friction coefficient d is only 0.22. In conclusion, the appropriate amount of graphene slurry can effectively improve the anti-corrosion performance of the nano-Ti polymer coating.
