Maleic anhydride grafted ethylene-propylene-diene terpolymer (EPDM-g-MAH) was prepared by grafting copolymerization method. Composite coatings with varied infrared emissivity were obtained by using copper (Cu) powder as inorganic pigments, either EPDM or EPDM-g-MAH as organic adhesive. The influences of the content of Cu powder and adhesive kinds on the infrared emissivity of the composite coatings were investigated. The as-prepared coatings were characterized by FTIR spectroscopy, infrared emissometer and SEM. The corrosion-resistant property of the coatings in aqueous 3.5 wt.% NaCl was assessed by the potentiodynamic polarization technique and electrochemical impedance spectroscopy (EIS). The results have shown that the interfacial interaction between EPDM and Cu is improved due to the MAH grafting on EPDM, benefiting from the compatibility of EPDM with Cu and the low porosity of EPDM/Cu coatings, which leads to the lower infrared emissivity and better corrosion-resistant property of the coatings.
