Abstract:
A passive radiative cooling hybrid film was created by embedding siloxane-functionalized metal-organic framework fillers into a porous polytetrafluoroethylene (PTFE) matrix. Benefiting from the micro-nano porous structure of PTFE and the extinction ability of rich Si-O bonds, the optimized film exhibits a high solar reflectance of approximately 98% and improved mid-infrared thermal emissivity of approximately 92%, achieving excellent cooling performance.
