This Small Business Innovation Research Phase I project will address the market-driven need for environmentally compatible marine antifouling coating technologies that outperform the state-of-the-art. Increasing environmental regulations have led to the banning of the most effective marine antifouling coatings which rely on toxicity as their mode of action. The best performing of these coatings contain heavy metal-based organometallics which when released into the environment persist, bioaccumulate, and affect non-target species. Increasing scrutiny of any type of heavy metal antifouling approach and growing concerns related to the use of even non-metal biocides has provided a product opportunity for our toxin-free technologies premised on a mechanistically different eco-friendly antifouling strategy. Our broad objective and anticipated outcome from our green chemistry process is the creation of commercially viable, eco-friendly antifouling surface technologies for biofouling control. By integrating advanced materials and manufacturing practices with a chemical biology perspective, we plan to create low cost, durable, self-polishing, low-settlement, foul-release coatings suitable for rigorous marine applications including ship hulls and energy producing offshore structures. Our coatings will employ both non-toxic and zero-volatile organic compound (VOC) systems ushering in new generation of highly effective antifouling technologies that are environmentally more responsible than current high-VOC, metal/biocide poisoning approaches.The broader impact/commercial potential of this project arises from a growing demand for green chemistry solutions to curtail biofouling of manmade structures. If left unchecked, the attachment and subsequent build-up of biofouling organisms, such as barnacles, will severely compromise the performance characteristics of structures such as ship hulls, aquaculture containment systems, and offshore energy-producing devices. Increased hydrodynamic drag on commercial hulls results in estimated excess fuels costs of 40 billion dollars annually and wastes natural resources and contributes to pollution. Economical antifouling technologies have the potential to disruption ecologically sensitive habitats and have shaped a product opportunity in a commercial space defined by price point, performance, and environmental regulations. Our transformative approach to developing effective, low cost, eco-friendly marine antifouling coatings evolved from a chemical biological and molecular mechanistic understanding of barnacle glue. When integrated with foul-release properties, durable coating chemistries capable of reducing settlement by preventing hardening of biofouler glue will result not only in a commercial product addressing a societal need but will also enhance our understanding of key scientific and technological principles underlying the marine biofouling problem. Participating professionals will benefit from multidisciplinary technical training in a 15 billion dollar marine coatings, ?green? collar jobs industry.

这一小型企业创新研究第一阶段项目将解决市场对环境兼容的海洋生物涂层技术的需求，这些技术优于最先进的技术。越来越多的环境法规导致最有效的海洋生物涂层被禁止，这些涂层依赖于毒性作为其作用模式。这些涂层的最佳性能包含重金属基有机金属，当释放到环境中时，会持续存在，生物累积并影响非目标物种。对任何类型的重金属杀菌方法的审查越来越严格，甚至对非金属杀菌剂的使用也越来越关注，这为我们的无毒技术提供了一个产品机会，该技术采用了一种不同的生态友好型杀菌策略。我们的绿色化学工艺的广泛目标和预期成果是创造商业上可行的、生态友好的生物污垢控制表面技术。通过将先进材料和制造实践与化学生物学观点相结合，我们计划创造低成本，耐用，自抛光，低沉降，污垢释放的涂层，适用于严格的海洋应用，包括船体和能源生产海上结构。我们的涂料将采用无毒和零挥发性有机化合物（VOC）体系，开创新一代高效防污技术，比目前的高VOC、金属/杀菌剂中毒方法更环保。该项目的更广泛影响/商业潜力来自于对绿色化学解决方案的日益增长的需求，以减少人造结构的生物污损。如果不加以控制，附着和随后积聚的生物污染有机体，如藤壶，将严重损害结构，如船体，水产养殖遏制系统，和海上能源生产设备的性能特征。对商用船体的增加的流体动力阻力导致估计每年400亿美元的额外燃料成本，浪费自然资源并造成污染。经济的可再生能源技术有可能破坏生态敏感的栖息地，并在由价格点，性能和环境法规定义的商业空间中形成了产品机会。我们开发有效、低成本、生态友好型海洋生物涂料的变革性方法源于对藤壶胶的化学生物学和分子机理的理解。当与污垢释放性能相结合时，能够通过防止生物污垢胶硬化来减少沉降的耐用涂层化学品不仅会产生满足社会需求的商业产品，而且还会增强我们对海洋生物污垢问题背后的关键科学和技术原理的理解。参与的专业人士将受益于多学科的技术培训，在一个15亿美元的海洋涂料，？绿色？白领产业
