Project description:
Chromogenic coating is the core technology for Smart Windows (SW), crucial for energy savings in future. In this project, we propose to combine chromogenic photochromic and thermochromic nanomaterials, creating a hybrid nanoparticles-based coating with enhanced visible transparency and high solar modulation. The primary goal is to achieve synergistic effects between the photochromic and thermochromic components, leading to a decreased transition temperature of the thermochromic material. This is accomplished by utilizing the additional energy absorbed from the solar spectrum and converted into thermal energy by the photochromic material. The aim is to achieve both high luminous transparency in the visible range and maintain high solar modulation in the NIR range, leveraging the paired chromogenic performance of the photochromic and thermochromic components. Furthermore, the NPs-based wet deposition technology allows for a significant reduction in fabrication costs compared to vacuum deposition, making SW more accessible for end-users. The key objective of this fundamental research project is to develop a cost-efficient and sustainable technology of high-performance hybrid chromogenic coatings for energy saving SW.
