Abstract    Biofouling on ships causes deleterious effects such as increased drag leading to reduced speed and increased fuel consumption. Controlling biofouling on ships is generally accomplished with biocide-based antifouling (AF) coating systems. One of the most commonly biocides is copper oxide [1]. Encapsulation of the biocides is a promising approach that may overcome some of the problems associated with the more traditional ways of incorporating the antifouling agent into the formulation [2]. Microencapsulated biocides in AF coating systems results shows biocides is more controlled which lower biocide release over longer periods of time than is possible with free biocides. This result is improved, extended, and environmentally friendly AF coating system performance [3]. In this study Copper oxide nanoparticles (CuO NPs) encapsulated with urea-formaldehyde (UF) by in situ polymerization method to controlled releasing biocides from marine coating. The results indicated that CuO NPs/UF microcapsules are the spherical and mononuclear structure and release rate of encapsulated CuO NPs with UF coating reduced 12.4% compared to non-encapsulated CuO NPs under the same conditions.
