This SBIR Phase II project aims to develop and commercialize a transparent, thin multifunctional coating for corrosion and biofouling prevention on coated surface. Its environmentally friendly product will be an efficient ready-to-use single component product that can be applied with ease, and would dry in ambient conditions without the need for external heating equipment. The global annual expenditure to mitigate corrosion is in the range of $2.5 trillion, roughly equal to 3.4% of the world's GDP. Protecting assets from corrosion is, hence, a critical requirement for all the industries. A broad range of applications can benefit from this coating technology such as aviation industry where removal of toxic chromium compounds from coating procedures is of high priority, automobile manufacturing where extended corrosion protection to vehicles without using toxic treatments is constantly sought, structural engineering where providing long life protection to bridges is always needed, marine engineering where protecting ships from corrosion and not contributing to ecological imbalance is long sought, military where minimizing the maintenance downtime of tanks and guns is of prime importance, hospitals that are interested in longer lasting medical implants, and paints and coating industry that is desiring removal of volatile organic components from their paints and coatings. The proposed coating is expected to offer scratch resistance and oleophobic characteristics in addition to corrosion protection. The initial success of this project will result in two high-volume products.This project aims to develop a specialized single-part, ready-to-use, nominally bioceramic liquid coating for protection against corrosion and fouling activities. On application over desired surface, this transparent liquid transforms into hard-yet-flexible coating. This thin coating composition consists of in-place generated nanoparticles of organometallic compounds in the 3D network of polysilsesquioxane. The reactivity of the precursor to coating is designed such that material can react with substrates in ambient conditions and dries to solid film without the need of any external heating. The hardened coating adheres to most surfaces including metals, ceramics, plastics, glasses, and wood. The optimum thickness of coating is approximately ten microns and can impart various desired surface functionalities to the coated object. In this project, efforts are directed towards optimization of current composition to be compatible with broad range of commercially available topcoat materials. The optimized coating composition will be subjected to a rapid properties screening before third party testing, validation and approvals. An extensive field testing will be conducted in collaboration with potential customers. This innovative coating technology will initially result into two products that can be used in place of carcinogenic hexavalent chromium compounds that are currently in use for the corrosion protection of metals. While one of the products would act as a corrosion prevention compound that can adhere to commercial topcoat paints, the other would act as self-cleaning coating to prevent biofouling activities.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.

SBIR 二期项目旨在开发一种透明、薄的多功能涂层并将其商业化，用于涂层表面的腐蚀和生物污垢预防。其环保产品将是一种高效的即用型单组分产品，可以轻松使用，并且可以在环境条件下干燥，无需外部加热设备。全球每年用于减轻腐蚀的支出约为 2.5 万亿美元，大约相当于世界 GDP 的 3.4%。因此，保护​​资产免受腐蚀是所有行业的关键要求。广泛的应用可以受益于这种涂层技术，例如航空工业，其中从涂层程序中去除有毒铬化合物是重中之重；汽车制造，不断寻求在不使用有毒处理的情况下对车辆提供扩展的腐蚀保护；结构工程，始终需要为桥梁提供长寿命保护；海洋工程，长期寻求保护船舶免受腐蚀且不造成生态失衡；军事领域， 对于对更持久的医疗植入物感兴趣的医院以及希望去除油漆和涂料中的挥发性有机成分的油漆和涂料行业来说，最大限度地减少坦克和枪支的维护停机时间至关重要。除了腐蚀保护之外，所提出的涂层预计还具有耐刮擦和疏油特性。该项目的初步成功将产生两种大批量产品。该项目旨在开发一种专门的单件、即用型、名义上的生物陶瓷液体涂料，用于防止腐蚀和污垢活动。当涂在所需表面上时，这种透明液体会转变成坚硬而柔韧的涂层。这种薄涂层组合物由聚倍半硅氧烷 3D 网络中就地生成的有机金属化合物纳米颗粒组成。前体对涂层的反应性经过设计，使得材料可以在环境条件下与基材反应并干燥成固体膜，而不需要任何外部加热。硬化涂层可粘附到大多数表面，包括金属、陶瓷、塑料、玻璃和木材。涂层的最佳厚度约为十微米，可以赋予涂层物体各种所需的表面功能。在该项目中，我们致力于优化当前的成分，使其与广泛的市售面漆材料兼容。优化后的涂料组合物将在第三方测试、验证和批准之前进行快速性能筛选。将与潜在客户合作进行广泛的现场测试。这种创新的涂层技术最初将产生两种产品，可用于替代目前用于金属腐蚀防护的致癌六价铬化合物。其中一种产品将充当可以粘附在商业面漆上的防腐化合物，而另一种产品将充当自清洁涂层以防止生物污垢活动。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
