Development of Environmentally Acceptable Nano-Hybrid Coatings for Bio-Fouling Protection

Abstract:

Alternative coatings should be as effective as conventional paints but with lower toxicity. In the present study, a commercially available epoxy resin modified with non functionalized nanozinc oxide (nZnO) was examined to get information on its antifouling and anti-corrosive properties. Epoxy nanohybrid coating was synthesized using nZnO (in the amount of 0wt%, 1wt%, 3wt%, 5wt%, 7wt% and 10wt%) and diglycidyl ether of bisphenol A (DGEBA) type of epoxy resin. The curing behavior of these materials was ascertained from FT-IR spectral studies. The anti-corrosive properties of the nanohybrid were investigated using salt spray and electro chemical polarization studies. The surface morphology images were taken by SEM analysis. This study indicates that nZnO particles were dispersed homogenously through the polymer matrix. The nZnO incorporated coating was found to exhibit enhanced anticorrosive performance. Approximately 50% reduction in fouling attachment was achieved with coatings containing 3wt% of nZnO.
