a R̅solar after accelerated soiling test based on ASTM D7897-18 standard, equivalent to 3 years of natural soiling. The soiled AACP coating demonstrated almost intact R̅solar compared with the unsoiled one. Insets present visual appearances of the coating samples before and after soiling. b Measurements of coating temperature showing excellent anti-soiling performance of the AACP coating (August 23rd, 2021, Chengdu). c Viscous mud dripped and flowed off the AACP coating showing excellent self-cleaning function. d The almost unchanged optical and wetting properties of AACP coating after 1000 h of UV exposure (0.89 W m−2 at 340 nm and 60 °C), equivalent to 1 year of Florida natural sunshine.
