该创新技术转化伙伴关系（PFI-TT）项目的更广泛影响/商业潜力是创造能够在高温下排斥液体和熔融聚合物的自修复、拒液表面涂层。潜在的应用包括燃料运输、化学加工、汽车零部件、热交换器、厨房电器和打印机。2019年，全球3D打印市场规模估计为115.8亿美元，预计从2020年到2027年将大幅增长。提出的不粘表面涂层将防止高温下各种印刷材料的粘附，使印刷性能更快，更有效。该项目的教育成果包括培训下一代科学家和工程师，并为他们提供必要的技能，以便在新颖，高影响力技术的翻译和商业化方面做出重大贡献。该项目旨在进一步推进液体排斥表面涂层技术，开发在高温下可以排斥液体和熔融聚合物的自修复和自清洁涂层。耐用和高温液体驱避表面在许多消费者和工业应用中很重要。这种表面涂层的发展仍然是一个挑战。在文献中或商业领域中，很少有表面涂层能够同时表现出高温液体驱避和自愈功能。在这个PFI-TT项目中，将系统地研究热自修复涂层技术在高温下排斥不同液体和熔融聚合物的能力，以及其自修复和自清洁特性。此外，还将进一步优化涂层配方和应用参数，以提高涂层的应用效率。一种能够抵抗高温液体和熔融聚合物的自修复表面涂层的成功演示，不仅将推动不粘表面涂层技术领域的发展，而且还将影响从厨房电器到3D打印的多个消费者和工业应用。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。

The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to create self-healing, liquid-repellent surface coatings capable of repelling liquids and melted polymers at elevated temperatures. Potential applications include fuel transportation, chemical processing, automotive parts, heat exchangers, kitchen appliances, and printers. The worldwide 3D printing market size was estimated to be $11.58 billion in 2019 and is anticipated to grow significantly from 2020 to 2027. The proposed non-stick surface coatings will prevent adhesion from various printing materials at high temperature, enabling faster and more efficient printing performance. The educational outcomes of this project include training the next generation of scientists and engineers and equipping them with the necessary skill sets to make substantial contributions in the translation and commercialization of novel, high-impact technologies.The proposed project aims to further advance the liquid repellent surface coating technologies by developing self-healing and self-cleaning coatings that can repel liquids and melted polymers at high temperature. Durable and high temperature liquid repellent surfaces are important in many consumers and industrial applications. The development of such surface coatings remains a challenge. Very few surface coatings reported in the literature or in the commercial space have demonstrated both high temperature liquid repellency and self-healing functionality. In this PFI-TT project, the thermally self-repairable coating technology will be ability to repel different liquids and melted polymers at high temperatures as well as their self-healing and self-cleaning characteristics will be systematically investigated. In addition, the coating formulations and application parameters will be further optimized to enhance the coating application efficiency. The successful demonstration of a self-healing surface coating that can repel high temperature liquids and molten polymers not only will advance the field of non-stick surface coating technologies but will also impact multiple consumers and industrial applications ranging from kitchen appliances to 3D printing.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.
