SBIR Phase II: Durable Superhydrophobic Smart Coating with Active Corrosion Protection

小型企业创新研究(SBIR)第二阶段项目的更广泛影响/商业潜力是显著改善对能源和交通行业至关重要的金属资产的防腐性能。腐蚀会导致金属结构失去结构完整性，对人类安全和周围环境构成威胁。金属腐蚀在全球的成本估计为2.5T美元，美国的成本约占25%。使用特殊材料的耐用、防腐、高度防水的涂料可能会以保护环境的方式将石油平台和船舶上涂料的使用寿命延长一倍。这延长了维护周期，并将资产生命周期维护成本降低了高达50%。高性能还将减少涂层数量，每个维护周期减少高达25%的人工成本。这项技术将提高结构安全性，减少维护频率，延长运行寿命，改善环境特性，降低金属资产的运营和维护成本。这项小企业创新研究二期项目进一步将超疏水智能颗粒涂料转化为高性能防腐涂料。这些超疏水颗粒提供了新的按需释放缓蚀剂(主动防腐)和超疏水(被动防腐)为一种多功能材料，与目前的实践状态不同。该技术的平台性使其能够包含多种类型的缓蚀剂，以保护脆弱的海洋环境。然后，智能颗粒可以被结合到许多现有的涂层系统中，以提供耐用、防腐和高度防水的独特组合。该项目将优化生产流程，并进行验证和验证测试。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to dramatically improve the corrosion protection of metal assets vital to the energy and transportation industries. Corrosion contributes to the loss of structural integrity of metal structures, which poses a risk to human safety and the surrounding environment. Metal corrosion costs an estimated $2.5 T globally, with US costs representing roughly 25%. Durable, anticorrosive, highly water-repellent coatings using special materials can potentially double the lifetime of coatings on oil platforms and ships in a way that protects the environment. This extends maintenance cycles and reduces asset lifetime maintenance costs up to 50%. The high performance will also reduce the number of coating layers, reducing labor costs up to 25% per maintenance cycle. This technology will improve structural safety, reduce maintenance frequency, lengthen the operating lifetimes, improve environmental characteristics, and reduce the costs of operating and maintaining metal assets.This Small Business Innovation Research Phase II project further translates coatings of superhydrophobic smart particles for high-performance anticorrosion paints. These superhydrophobic particles offer new on-demand release of corrosion inhibitors (active corrosion protection) and superhydrophobicity (passive corrosion protection) into one multi-functional material, unlike current state of practice. The platform nature of the technology enables inclusion of numerous types of corrosion inhibitors to safeguard delicate marine environments. Smart particles can then be incorporated into many existing coating systems to deliver a unique combination of durable, anticorrosive, and highly water-repellent coatings. This project will optimize production processes and conduct verification and validation tests.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.
