Effect of Nano-ZnO on Properties of Anti-Fouling Coatings Based on FEVE Coploymer

Abstract

To develop anti-fouling coatings, the effect of nano-ZnO on properties of coatings based on FEVE copolymer was investigated in the paper. 8 coatings were prepared with controlling the content of nano- ZnO respectively 0%, 2%, 4%, 6%, 8%, 10%, 15% and 20 wt %. The mechanical properties and hydrophobicity of coatings were measured. Morphology of coatings were observed by SEM. Roughness was measured at the centre of along diagonal with rugosimeter Hommel T-6000. The results showed that nano-ZnO influences gloss, impact-resistance, and hydrophobicity of coatings. It does’t influence obviously the adhesive of the coatings to substract. The hydrophobicity and roughness of coatings increases with the augment of content of nano-ZnO in coatings. The impact-resistance decreases with the augment of content of nano-ZnO in coatings. When the content of nano-ZnO exceeds 15%, the surface roughness of coatings gets obviously bigger.
