Abstract

Composite emulsion coating with polyaniline and core-shell fluorine-containing polyacrylate emulsion (PANI/ FPAc) was prepared for protecting Q235 steel in this paper. The structure of PANI emulsion particles and core-shell FPAc emulsion particles was observed by transmission electron microscope (TEM). The hydrophobic properties of the composite emulsion coatings were tested by contact angle tester. Electrochemical methods such as electrochemical impedance spectroscopy (EIS) and Tafel curve were used to evaluate the anticorrosion performance of the composite emulsion coatings. The results showed that PANI/FPAc composite emulsion coating had better anticorrosion properties when its proportion reached 1:1.
