项目摘要

This Faculty Early Career Development Program (CAREER) grant will promote the progress of science by contributing new knowledge related to a novel manufacturing process for fabricating composite materials for a variety of applications in the energy, infrastructure, aerospace, chemical and automotive industries. Composite materials are made by combining two or more materials, the combination of which provides enhanced electrical, mechanical, chemical, and/or surface properties. Understanding how to control the processing of composite materials enables customized performance for a broad range of critical applications. There are many manufacturing processes to make composite materials. However, most require multiple process steps and require the use of significant energy and chemicals, both of which are costly and wasteful. This grant supports fundamental research to provide new knowledge about a novel light irradiation process that will enable rapid, scalable, and controllable manufacturing of composite materials made from polymers and ceramics with lower cost and energy usage. This multidisciplinary research integrates manufacturing, chemistry, and materials science and will help broaden the participation of underrepresented groups in research and positively impact engineering education.The light-induced self-writing of composite material architectures can overcome several limitations of existing manufacturing techniques, such as high cost, high energy usage, multiple steps, and lack of microscale control over morphology. However, some scientific barriers prevent the realization of the full application potential of light-induced self-writing for additive manufacturing of composite material architectures. This research aims to fill the knowledge gap on the processing-structure-property relationship and the microstructure formation mechanisms for self-writing polymer-inorganic composite material architectures. Experiments will be performed to establish relationships between process parameters and composite morphology to test the hypothesis that self-writing can regulate morphology evolution in terms of reaction and diffusion kinetics. A multi-physics model will be developed to simulate morphology formation and predict final structure as a function of process parameters. Application demonstrations will include materials for superhydrophobic surfaces, lithium-ion batteries, and ultra-light mechanical structures. The educational program will focus on secondary education by providing workshops for high school teachers and research experiences for high school students as well as Masters of Education graduate students, with a focus on recruiting from groups underrepresented in STEM.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.

该教师早期职业发展计划（CAREER）拨款将通过贡献与新型制造工艺相关的新知识来促进科学的进步，该工艺用于制造复合材料，用于能源，基础设施，航空航天，化学和汽车行业的各种应用。复合材料通过组合两种或更多种材料制成，其组合提供增强的电、机械、化学和/或表面性质。了解如何控制复合材料的加工过程，可以为广泛的关键应用提供定制的性能。有许多制造工艺来制造复合材料。然而，大多数需要多个工艺步骤，并需要使用大量的能源和化学品，这两者都是昂贵和浪费的。该补助金支持基础研究，以提供有关新型光照射过程的新知识，该过程将使由聚合物和陶瓷制成的复合材料的快速，可扩展和可控制造具有更低的成本和能源使用。这种多学科的研究整合了制造，化学和材料科学，将有助于扩大在研究中的代表性不足的群体的参与，并积极影响工程教育。复合材料结构的光诱导自写可以克服现有制造技术的几个局限性，如高成本，高能耗，多步骤，以及缺乏对形态的微观控制。然而，一些科学障碍阻止了光诱导自写入用于复合材料架构的增材制造的全部应用潜力的实现。本研究旨在填补自写入聚合物-无机复合材料体系结构的加工-结构-性能关系和微观结构形成机理的知识空白。将进行实验，以建立工艺参数和复合材料形态之间的关系，以测试的假设，自写入可以调节形态演变的反应和扩散动力学。将开发多物理模型来模拟形态形成并预测作为工艺参数的函数的最终结构。应用演示将包括超疏水表面材料、锂离子电池和超轻机械结构。该教育计划将通过为高中教师提供研讨会和为高中生以及教育硕士研究生提供研究经验，重点关注STEM中代表性不足的群体。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。
