The broader impact/commercial potential of this I-Corps project is the development of coatings for preservation, architecture, masonry, marine, aerospace, and automotive industries. Currently employed protective coatings often have long curing times leading to debris contamination, and typically have a short pot life. The proposed technology is designed to provide more rapid curing as well as storage as a one-pot solution for over one year with repeated usage. There is a need to preserve and protect bronze plaques and lithography on headstones. In addition, anti-fouling capabilities are of interest in the protective and marine coatings industries. For architecture and masonry, the proposed technology may prevent and/or reduce environmental effects on surfaces and provide flame resistance for wooden structures ensuring future generations will have access to these cultural experiences. For the marine industry, the proposed coating may increase fuel efficiency by reducing adhesion and transport of invasive marine organisms, and its graffiti resistance may limit offensive content and decrease maintenance needs.This I-Corps project is based on the development of silicon-based, tri-cure coating technology. The proposed technology uses three distinct curing methodologies to undergo a rapid (30-minute) non-impressionable surface upon exposure to UV light (lamp or sun) that is quickly followed by secondary and tertiary cures that occur more slowly, enhancing adhesion and stability. Test results show that upon application, sunlight produces a non-sticky surface within 30 minutes, with complete protection within 24 hours that lasts more than 2 years using a single coat. In addition, the stability of the base coating solution and its recyclability reduce wasted resources. The proposed coating has been found to provide these characteristics to a treated surface: hydrophobicity, flame resistance and self-extinguishing, efflorescence and oxidation resistance, fungal and Mollusca growth/attachment resistance, microbial inhibition, anti-graffiti, and photo, thermal, and chemical stability. It also has been shown to adhere strongly to most surfaces, is non-toxic, comes in a single container, requires no mixing, is stable for multiple years, and may be applied by dipping, spraying, or wiping on numerous surfaces. This may offer a highly versatile coating to expand preservation methods.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.

该 I-Corps 项目更广泛的影响/商业潜力是开发用于防腐、建筑、砖石、海洋、航空航天和汽车行业的涂料。目前使用的保护涂层通常具有较长的固化时间，导致碎屑污染，并且通常具有较短的适用期。 所提出的技术旨在提供更快速的固化以及作为一锅解决方案的存储时间超过一年并可重复使用。 需要保存和保护墓碑上的青铜匾和石版画。此外，防污能力也受到防护涂料和船舶涂料行业的关注。 对于建筑和砖石建筑，所提出的技术可以防止和/或减少环境对表面的影响，并为木结构提供阻燃性，确保子孙后代能够获得这些文化体验。 对于海洋工业，所提出的涂层可以通过减少入侵海洋生物的粘附和运输来提高燃料效率，并且其抗涂鸦性可以限制攻击性内容并减少维护需求。该 I-Corps 项目基于硅基、三固化涂层技术。 所提出的技术使用三种不同的固化方法，在暴露于紫外线（灯或太阳）时快速（30 分钟）形成不可印象的表面，然后迅速进行速度较慢的二级和三级固化，从而增强粘附力和稳定性。 测试结果表明，涂​​抹后，阳光下30分钟内即可产生不粘表面，24小时内即可获得完全保护，单层涂层可持续使用2年以上。 此外，底漆溶液的稳定性及其可回收性减少了资源浪费。已发现所提出的涂层可为处理过的表面提供以下特性：疏水性、阻燃性和自熄性、抗风化性和抗氧化性、抗真菌和软体动物生长/附着性、微生物抑制性、防涂鸦性以及光、热和化学稳定性。 它还被证明可以牢固地粘附在大多数表面上，无毒，装在一个容器中，无需混合，可稳定多年，并且可以通过浸渍、喷涂或擦拭的方式应用于多种表面。 这可能会提供一种高度通用的涂层来扩展保存方法。该奖项反映了 NSF 的法定使命，并且通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
