CAREER: Structure-property-processing Relationships for Waterborne Non-isocyanate Thermal Insulating Coating

这个CAREER项目的动机是需要开发环境友好的合成方法，为下一代多功能“绿色”涂料。本研究将水性非异氰酸酯聚氨酯（WNIPUs）技术与功能性无机颜料相结合，实现水性非异氰酸酯聚氨酯保温涂料。 将研究结构-性能-加工关系，以了解非异氰酸酯方法、着色机理、水性涂料形成和着色。该研究将与支持阿克伦大学腐蚀工程项目的教育活动以及旨在吸引女学生进入STEM职业的推广活动相结合。拟议的研究项目将侧重于了解WNPU隔热涂料的结构-性能-加工关系。以植物油为原料合成了一种性能可调的水性非异氰酸酯脲醛醇酸树脂。本研究的目的将是获得新的见解聚合反应动力学和结构性能的关系。为了开发能够反射近红外辐射（NIR）并呈现多种颜色的涂料，将通过用金属离子掺杂/共掺杂传统无机颜料来获得三种新型的热稳定和紫外稳定的NIR反射无机颜料。研究掺杂元素与颜料性质的结构-性质关系，以了解颜料的着色机理。通过研究颜料的分散和成膜过程，建立性能-加工关系，以获得理想的涂层性能。将通过一个集科研和教育于一体的本科生高级设计项目对所生产的水性非异氰酸酯基聚氨酯保温涂料的应用进行评估。对聚合过程的科学理解将导致通过非异氰酸酯方法设计水性涂料的框架，这将有助于取代异氰酸酯基涂料。本研究的结果可以潜在地转移到其他使用无机颜料的水性涂料体系中。将开发一门关于可持续涂料的新课程，以丰富阿克伦大学腐蚀工程项目的课程，这是美国第一个此类本科项目。拟议的教育和推广活动包括“绿色涂料101”研讨会、女性参与工程夏令营以及旨在吸引女性学生进入STEM职业的高中生夏季研究机会。该奖项反映了NSF的法定使命，并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。

This CAREER project is motivated by the need for developing environmentally-friendly synthesis methods for next-generation multifunctional 'green' coatings. This proposed research will integrate waterborne non-isocyanate polyurethanes (WNIPUs) technology with functional inorganic pigments to achieve a waterborne non-isocyanate thermal insulating uralkyd coating. Structure-property-processing relationships will be investigated to understand the non-isocyanate approach, coloration mechanism, and waterborne coating formation and pigmentation. The research will be integrated with educational activities supporting the Corrosion Engineering program at The University of Akron and outreach activities aimed at attracting female students into STEM careers.The proposed research project will be focused on understanding the structure-property-processing relationships of a WNPU thermal insulating coating. A waterborne non-isocyanate uralkyd with tunable properties will be synthesized by using vegetable oils as the feedstock. The objective of the study will be to gain new insights into the polymerization reaction kinetics and structure-property relationships. To develop coatings that can reflect near-infrared radiation (NIR) and exhibit a variety of colors, three new types of NIR-reflective inorganic pigments that are thermally- and UV-stable will be obtained by doping/co-doping traditional inorganic pigments with metal ions. The structure-property relationships of the doping elements and the pigment properties will be studied to understand pigment coloration mechanisms. The property-processing relationships will be established by studying the processes of pigment dispersion and film formation to achieve desirable coating properties. An application of the produced waterborne non-isocyanate thermal insulating uralkyd coating will be evaluated through an undergraduate senior design project that integrates research and education. The scientific understanding of the polymerization process will lead to a framework for designing waterborne coatings through a non-isocyanate approach that will facilitate the replacement of isocyanate-based coatings. The results of this study can be potentially transferred to other waterborne coating systems that use inorganic pigments. A new course on sustainable coatings will be developed to enrich the curriculum of the Corrosion Engineering program at The University of Akron, the first undergraduate program of its kind in the US. Proposed educational and outreach activities include a 'Green Coatings 101' workshop, women-in-engineering summer camps, and summer research opportunities for high school students aimed at attracting female students into STEM careers.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.
