Surface of copper (Cu) powder was chemically modified using silane coupling agent (KH550) in order to improve the interfacial interaction between Cu and polyurethane (PU) polymer, and therefore, expectable corrosion resistance of the Cu/PU coating with low infrared emissivity was acquired. Infrared spectra reveal an obvious interaction between Cu and PU induced by the addition of KH550. The corrosion behavior of Cu/PU coating has been investigated with potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Results have shown that the proper amount of KH550 is benefit to the dispersion of Cu and induces the strong chemical interfacial interaction, which often keeps the low infrared emissivity and increases the corrosion resistance of the Cu/PU coating.
► KH550 is benefit to the dispersion of Cu. ► KH550 induces the strong chemical interfacial interaction. ► Expectable corrosion resistance of low infrared emissivity coating was acquired.
