项目摘要

Research Objectives and ApproachesThe objective of this research is to create a new form of holographic polymer film that can redirect sunlight over daily and yearly variations in order to enable passive solar concentrators for energy generation and passive solar lighting for energy conservation. The approach is to tailor the polymer reaction and diffusion rates such that the holograms can grow to 25 times the efficiency typical of such materials, enabling many thin and 100% efficient films to be stacked into a single sheet. Design tools for these angle and color selective films will be created to guide the fabrication and test of functional samples.Intellectual MeritThe research will advance soft materials science by investigating optically-initiated, strong segregation of polymers in solid films. Specialized theoretical and numerical design tools will exploit this enhanced control over 3D material properties to enable new classes of polymer optical devices with large refractive index gradients. High-throughput film fabrication processes will be created to realize these designs in economically-relevant costs and sizes. In cooperation with two industrial partners, the program will then fabricate and test specialized films for solar generation and conservation applications.Broader ImpactsThe program will establish a satellite research hub at an undergraduate liberal arts college. Undergraduates will investigate materials during the academic year, then spend summers integrating results into the larger program at the University of Colorado.

研究目标和方法本研究的目标是创造一种新型全息聚合物薄膜，它可以在每日和每年的变化中重新定向阳光，从而使被动式太阳能聚光器能够产生能量，并使被动式太阳能照明能够实现节能。该方法是调整聚合物反应和扩散速率，使全息图可以增长到此类材料典型效率的 25 倍，从而使许多薄且 100% 高效的薄膜能够堆叠成单片。将创建这些角度和颜色选择性薄膜的设计工具，以指导功能样品的制造和测试。智力价值该研究将通过研究固体薄膜中聚合物的光学引发的强偏析来推进软材料科学。专业的理论和数值设计工具将利用这种对 3D 材料特性的增强控制来实现具有大折射率梯度的新型聚合物光学器件。将创建高通量薄膜制造工艺，以经济相关的成本和尺寸实现这些设计。该计划随后将与两个工业合作伙伴合作，制造和测试用于太阳能发电和节能应用的专用薄膜。更广泛的影响该计划将在一所本科文理学院建立一个卫星研究中心。本科生将在学年期间研究材料，然后利用暑假将结果整合到科罗拉多大学的更大项目中。
