Dopamine Modified Metal-Organic Frameworks on Anti-corrosion Properties of Waterborne Epoxy Coatings

In this study, dopamine (DA) was grafted on the surface of the Metal-Organic Frameworks (MOFs) and DA-MOFs were incorporated into waterborne epoxy coatings. The DA-MOFs were characterized using infrared spectroscopy, Thermogravimetric Analysis (TG), and X-ray diffraction (XRD). The coating properties was studied by using electrochemical impedance spectroscopy(EIS), salt spray test and adhesion test. Compared with epoxy resin coatings, coatings with DA-MOFs enhanced the properties of water resistance and corrosion resistance. The EIS results showed that the resistance value of coating with DA-MOFs was above 3.18 × 108 Ω cm2. Corrosion protection performance of epoxy coating with 0.5 wt% DA-MOFs was higher than others.
