摘要：

The commercial enzymes complex and bacterial metabolites as antifouling additives were incorporated into a vinyl chloride-vinyl acetate copolymer UM50-based and epoxy resin-based paints. Fouling field tests, electrochemical impedance spectroscopy (EIS) and polarisation measurements showed that the addition of biocomponents into coatings did not always improve corrosion resistance. The EIS data demonstrated that the highest corrosion protection was observed when bacterial metabolites were added into UM50-based coatings and enzyme complexes into epoxy-based paint.
