The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Phase II project is the development of a novel non-toxic antifoulant that keeps the hulls of vessels clear of biofouling without the environmental harm imposed by today's current antifoulant products. Biofouling is the accumulation of algae, barnacles, and other marine organisms on underwater surfaces such as the hulls of ships and boats. A ship with a biofouled hull experiences drag, which slows it down and drives up fuel consumption by as much as 40%. For the global shipping industry, this increase imposes an annual fuel cost penalty of $36 billion. Moreover, the excess fuel consumption due to biofouling adds 386 million tons of CO2 emissions to the atmosphere. Over 90% of antifoulants in the market today contain copper, a toxic biocide harmful to the marine ecosystem. This project will develop a competitive antifoulant which avoids harmful environmental impacts.This Small Business Technology Transfer (STTR) Phase II project develops a first-of-its-kind antifouling marine coating that is high-performing and safe for use in aquatic ecosystems. This antifouling coating contains no biocides but delivers antifouling performance matching that of the market leading copper coatings. The novel coating consists of a hydrophilic polymeric material that is naturally antifouling. It prevents biofouling by creating a liquid barrier around a surface which masks the surface from fouling marine organisms. While other hydrophilic coatings are notoriously unstable in aqueous environments, this innovation includes a method of application that helps to greatly increase the coating's stability and durability. The objectives of this Phase II project are to tune the formulation of the novel coating to meet marine end user performance requirements and regulatory benchmarks and to demonstrate small-batch production capabilities. The outcome of this work will be a rigorously tested, ready high-performing eco-friendly antifouling solution.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这一小型企业技术转移（STTR）II期项目的更广泛的影响/商业潜力是开发一种新型的无毒抗抗抗菌物，它可以使船体避免生物污染的船体，而不会受到当前当前的抗氟烷产品造成的环境伤害。 生物污染是藻类，藤壶和其他海洋生物在水下表面上的积累，例如船体和船只的船体。 一艘具有生物货运船体的船经历着阻力，它将其放慢速度，并将燃油消耗提高多达40％。 对于全球航运业而言，这一增长施加了360亿美元的年度燃料成本罚款。此外，由于生物污染而产生的过量燃油消耗增加了3.86亿吨大气的二氧化碳排放。 当今市场上有超过90％的抗蛋白含有铜，这是对海洋生态系统有害的有毒杀菌剂。 该项目将开发一种具有竞争性的反蒸馏器，避免了有害的环境影响。该小型企业技术转移（STTR）第二阶段项目开发了一种首要的反污染海洋涂层，在水生生态系统中使用高性能且可安全。 这种防污涂层不含杀菌剂，但可以提供与市场领先铜涂料相匹配的防污性能。新颖的涂层由一种自然抗污的亲水性聚合物材料组成。 它通过在表面上产生液体屏障来防止生物污染，从而从污染海洋生物的表面掩盖表面。尽管其他亲水性涂料在水性环境中却是不稳定的，但该创新包括一种应用方法，有助于大大提高涂层的稳定性和耐用性。该第二阶段项目的目标是调整新颖涂层的制定，以满足海洋最终用户绩效要求和监管基准，并展示小批量生产能力。 这项工作的结果将是一项严格测试的，现成的高绩效生态友好型反污点解决方案。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估审查标准来评估值得支持的。
