Abstract
En 中文
• A fluorine-free water-based PDRC paint was developed and tested. • BaSO4, Al2O3, SiO2 particles and glass bubbles are functional fillers. • Paint preparation by scalable and facile agitation processes. • Proposed PDRC paint exhibits a solar reflectance of 0.92 and an emissivity of 0.96. • Achieved 6℃ cooler than commercial white paint in extreme hot weather.
