The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to create a cost-effective, high-performance anticorrosive coating for protecting metal structures, particularly in marine environments. High value assets that are essential parts of the US energy infrastructure, such as offshore oil and gas platforms, marine ships and wind turbines, are exposed to one of the most corrosive environments with direct exposure to salt water via immersion and seawater spray. Corrosion of these metal structures is estimated to cost the world economy around $2.3 trillion in maintenance and replacement capital every year. This project's superhydrophobic coating has the potential to significantly reduce both cost and waste by improving structural safety, reducing maintenance frequency and lengthening the operating lifetime of such vital assets. It will also reduce the environmental impact of corrosion protection systems by using less harmful materials, negating coating repainting needs and extending metal lifetime.This Small Business Innovation Research (SBIR) Phase I project seeks to make a durable, superhydrophobic, high-performance anticorrosive coating through creation of dual-function coating additives. Coatings and corrosion inhibitors are generally the first line of defense in this fight against corrosion. Highly-water repellent superhydrophobic coatings are leading contenders for delivering a step change in corrosion protection performance. However, current solutions suffer from two notable issues: high cost and low durability in highly corrosive marine environments. Existing superhydrophobic coatings require complex and expensive equipment and materials. In addition, these coatings are easily damaged during use, resulting in the loss of their water repellency and corrosion protection ability. The key innovation of this project is a novel dual-function additive that can impart coatings with both superhydrophobicity (passive corrosion protection) and on-demand corrosion inhibitors release (active corrosion protection). This additive based approach results in a durable coating that retains its protective abilities even through significant use and abrasion and enables adaptation to many other coating applications, even ones outside of corrosion.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.

这个小企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是创造一种具有成本效益的高性能防腐涂层，用于保护金属结构，特别是在海洋环境中。作为美国能源基础设施重要组成部分的高价值资产，如海上油气平台、海洋船舶和风力涡轮机，都暴露在最具腐蚀性的环境中，通过浸泡和海水喷雾直接暴露在盐水中。据估计，这些金属结构的腐蚀每年使世界经济损失约2.3万亿美元的维护和更换资本。该项目的超疏水涂层有可能通过提高结构安全性、减少维护频率和延长这些重要资产的使用寿命来显著降低成本和浪费。它还将通过使用更少的有害材料，消除涂层重新喷涂需求和延长金属寿命，减少防腐系统对环境的影响。这个小型企业创新研究（SBIR）一期项目旨在通过创造双功能涂层添加剂来制造耐用、超疏水、高性能的防腐涂层。涂料和缓蚀剂通常是抵抗腐蚀的第一道防线。高度防水性超疏水涂料是实现防腐蚀性能阶梯式变化的主要竞争者。然而，目前的解决方案存在两个明显的问题：在高腐蚀性的海洋环境中，成本高，耐久性低。现有的超疏水涂料需要复杂而昂贵的设备和材料。此外，这些涂层在使用过程中容易损坏，导致其防水和防腐能力的丧失。该项目的关键创新是一种新型双功能添加剂，它可以赋予涂层超疏水性（被动腐蚀防护）和按需释放缓蚀剂（主动腐蚀防护）。这种以添加剂为基础的方法产生了耐用的涂层，即使经过大量使用和磨损，也能保持其保护能力，并且能够适应许多其他涂层应用，甚至是在腐蚀之外的应用。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
