This Small Business Innovation Research Phase I project will develop an environmentally benign yet highly effective marine antifouling coating for the American yacht market. The coating is a non-biocidal, foul release surface which does not require the vessel to move to obtain antifouling protection. It is a non-ablative multi-modal coating that will deter settling marine larvae when the vessel is stationary and will eliminate any attached marine organisms, such as barnacles through self-cleaning (e.g. fouling release) while underway. The commercial impact of the innovation will be in reducing consumption of non-renewable resources through increased fuel efficiency and possible expansion into additional markets. Such additional markets would include those for commercial vessels, Navy vessels, bridges, windmills, etc., while successfully reducing harmful chemicals in the marine environment. The market for these coatings is expected to double in the next four years, currently being at $10.2 billion. The findings from this development work will also be incorporated into research based educational programs. The intellectual merit of this project is the development of a promising synthetic conopeptide analog to the noradrenaline (NA) molecule. Prior art has shown that NA, when bound to a surface (or included as part of a coating covering a surface), deters fouling marine invertebrates from settling, thus preventing biofouling. Another distinct advantage of using conopeptide based systems is their stability in the marine environment. The current efforts are focused upon improving the efficacy and antifouling performance of these molecules. The phase I research objectives are (1) conjugation of the bioactive conopeptide additive to the current foul release coating; (2) demonstration of antifouling efficacy and proof of concept by bioassay; (3) development of batch coatings for scale-up for marine field tests. The results will be useful for designing new test coatings for scale up and testing in the marine environment.

这个小企业创新研究第一阶段项目将为美国游艇市场开发一种环保且高效的海洋防污涂料。该涂层是一种非杀菌剂，不需要容器移动以获得防污保护的恶臭释放表面。这是一种非烧蚀的多模态涂层，当船舶静止时，它将阻止海洋幼虫沉降，并在航行中通过自清洁（例如污垢释放）消除任何附着的海洋生物，如藤壶。这项创新的商业影响将是通过提高燃料效率和可能扩展到其他市场来减少不可再生资源的消耗。这些额外的市场将包括商业船只、海军船只、桥梁、风车等的市场，同时成功地减少海洋环境中的有害化学品。这些涂料的市场预计将在未来四年翻一番，目前为102亿美元。这项开发工作的结果也将被纳入基于研究的教育计划。该项目的智力优势在于开发了一种有前途的去甲肾上腺素（NA）分子的合成肽类似物。先前的技术已经表明，当NA结合到表面（或作为覆盖表面的涂层的一部分）时，可以阻止海洋无脊椎动物的沉降，从而防止生物污染。使用基于共肽的系统的另一个明显优势是它们在海洋环境中的稳定性。目前的工作重点是提高这些分子的功效和防污性能。第一阶段的研究目标是(1)将生物活性多肽添加剂偶联到现有的恶臭释放涂层中；(2)生物测定法的防污效果论证和概念验证；(3)开发用于海上现场试验的批量涂料。研究结果将有助于设计新的测试涂层，以扩大规模并在海洋环境中进行测试。
