Controllable fabrication of ZnO nanorods@cellulose membrane with self-cleaning and passive radiative cooling properties for building energy-saving applications

Recent Advances in Material Engineering and Applications for Passive Daytime Radiative Cooling

“…However, in addition to the basic requirement for PDRC performance, the materials used for building roof or exterior must also be evaluated for their properties including physical and chemical stability, mechanical property, [21,234] aesthetic function (color), [84,176,33,[187][188][189][190][191][192][193][194][195] self-cleaning performance, [99,235] fire-retardant and mold-proof performance, [234] scalability, [136,21,236] low-cost [237,238] and ecofriendliness. [29] Zhao et al [235] fabricated ZnO nanorods@cellulose membrane via in situ growth method for building daytime passive radiative cooling (Figure 22a,b). The membrane not only achieved remarkable daytime radiative cooling, but also had excellent selfcleaning properties (water contact angle >150° and rolling angle less than 7°).…”

“…The PDRC materials reviewed in chapter three can all be served as potential candidates for building cooling. However, in addition to the basic requirement for PDRC performance, the materials used for building roof or exterior must also be evaluated for their properties including physical and chemical stability, mechanical property, [ 21,234 ] aesthetic function (color), [ 84,176,33,187–195 ] self‐cleaning performance, [ 99,235 ] fire‐retardant and mold‐proof performance, [ 234 ] scalability, [ 136,21,236 ] low‐cost [ 237,238 ] and ecofriendliness.

Comfort Analysis of Hafnium (Hf) Doped ZnO Coated Self-Cleaning Glazing for Energy-Efficient Fenestration Application

“…Zinc oxide (ZnO) is one of the most bio-friendly important semiconductors that have been investigated for self-cleaning applications. A superhydrophobic ZnO nanorods@cellulose membrane for efficient building radiative cooling was investigated [ 35 ]. ZnO-coated transparent wood was employed for building applications previously and showed 17% energy saving compared to a traditional window [ 36 ].…”
