Cold Spray Modification of ZnO-Cu Coatings for Bacterial Attachment Inhibition

Abstract:

This research work describes the processing of antibacterial and hydrophobic feedstock suitable for marine antifouling coatings. A composition of agglomerated ZnO-Cu powder and respective produced coatings were evaluated for fouling properties via antimicrobial activity test. Wettability of coating was also determined by contact angle measurements. These new antifouling coatings aim to prevent the growth of biofilm, reduce biofouling and improve both maintenance cost and fuel efficiency of the maritime structures and vessels. It should be able to extend dry docking cycle by providing an alternative environmentally compliant coating that is long lasting compared to conventional paint coatings. The results showed that ZnO and copper composites inhibit the C. marina attachment on the coating surfaces.
