This project is developing and demonstrating a dynamic window film prototype that switches between transparent and diffusely reflective states. The key element in this prototype is reversible reflectance switching, which has been previously demonstrated in a partial device format and on rigid glass substrates. This project will integrate this early result into a flexible prototype structure that will be used to demonstrate a reversibly switchable reflective electrochromic device on a flexible substrate. The result will be a 3-inch-by-3-inch laminated, flexible, dynamic window film prototype that switches between transparent and diffusely reflective states and includes full characterization of the specular and diffuse optical performance in the visible and near-infrared.
