The research objective of this project is to develop polymerization chemistry for light-mediated control of the shape of a surface coating. This comprehensive study of a new class of monomers and polymer coatings will provide new insights and new capabilities in the field of nano- and micro-structures that change shape in response to light. We expect the development of this field of materials chemistry to enable the selective deposition of controlled-thickness films over many geometrically-complex actuation modes not currently accessible with traditional solution casting methods, overcoming a major technological hurdle associated with this exciting class of materials. The approach of this research will be to 1) use computational methods to evaluate the behavior of the proposed materials with experimental synthesis and characterization of the materials to rationally design a new class of light-responsive monomers, 2) evaluate speed and spatial control over coating formation, and 3) elucidate the governing principles of actuation of these coatings over complex nanoscale geometries.If successful, this research will bridge the gap between two-dimensional actuatable materials and applications in devices as varied as artificial muscle motion, switchable surface adhesion, and directed fluid flow. Graduate students will be trained through the execution of this research. Undergraduate students will be trained in association with this project and an existing Research Experiences for Undergraduates program at the University of Kentucky. The computational effort will also integrate into ongoing outreach activities at Kentucky-based non-PhD granting institutions. The PIs will continue to attract and retain qualified undergraduate and graduate researchers from underrepresented minorities for the advancement of the proposed work. Finally, this work supports the development of an educational program in surface characterization and analysis for painting professionals at local and national automotive manufacturing facilities.

本项目的研究目标是开发用于光介导的表面涂层形状控制的聚合化学。对一类新的单体和聚合物涂层的全面研究将在响应光而改变形状的纳米和微米结构领域提供新的见解和新的能力。我们期望材料化学这一领域的发展能够在许多几何形状复杂的致动模式上选择性地沉积厚度可控的薄膜，这是传统的溶液浇铸方法目前无法实现的，克服了与这类令人兴奋的材料相关的主要技术障碍。这项研究的方法将是1）使用计算方法来评估所提出的材料的行为，并对材料进行实验合成和表征，以合理设计一类新的光响应单体，2）评估涂层形成的速度和空间控制，以及3）阐明这些涂层在复杂的纳米几何形状上的驱动原理。如果成功，该研究将弥合二维可致动材料与如人工肌肉运动、可切换表面粘附和定向流体流动等各种装置中的应用之间的差距。研究生将通过这项研究的执行进行培训。本科生将接受与本项目和肯塔基州大学现有的本科生研究经验项目相关的培训。计算工作也将纳入正在进行的外展活动，在奥克兰的非博士授予机构。PI将继续吸引和留住来自代表性不足的少数民族的合格本科生和研究生研究人员，以推进拟议的工作。最后，这项工作支持在表面表征和分析的教育计划，在当地和国家的汽车制造设施的油漆专业人员的发展。
