encapsulation of zinc oxide nanoparticles with poly methyl methacrylate as biocides is an easy strategy to decrease of marine pollution

Most antifouling coatings are based on biocide paints, although antifouling coatings (afc) are a potential source of marine pollution, they also have potential environmental benefits in aquatic ecosystems as tools for prevention or mitigation of the dispersal and establishment of nonnative species [1]. zinc oxide in addition to biocidal properties in anti-fouling coatings, that can be included as an extender or pigment, can improve coating performance and work as an erosion prevention [2]. nanoscience and nanotechnology open up new opportunities for the development of new products with exceptional properties. the applications of nanotechnology in the field of coating can facelift the coating industry [3]. nanocapsules in afc can protect biocides from environmental effects and controlling releasing biocides to marine environment. in this research zno nps were prepared by co-precipitation method and then, zno nps encapsulated with poly methyl methacrylate (pmm) via in-situ suspension polymerization. the release of zinc ions into the seawater was measured by icp-aes at different times. results show release rate of zno nps/pmma reduced 20.84% compared to free zno nps under the same conditions.

In this research ZnO NPs were prepared by co-precipitation method and then, ZnO NPs encapsulated with poly methyl methacrylate (PMM) via in-situ suspension polymerization. The release of zinc ions into the seawater was measured by ICP-AES at different times. Results show release rate of ZnO NPs/PMMA reduced 20.84% compared to free ZnO NPs under the same conditions.
