Multi-bioinspired self-cleaning energy-free cooling coatings

Abstract

Energy-free cooling coatings present great potential to reduce global energy consumption, in which passive daytime radiative cooling (PDRC) without the use of additional electricity is promising. In spite of exciting...

A review on emerging developments in thermal and moisture management by membrane‐based clothing systems towards personal comfort

“…It seems though the weaving or knitting of these multi‐component yarns faces many problems due to exposure to severe tensile and abrasion stresses in industrial machines. It seems these proposed scenarios are limited by poor opto‐thermal stability forced by the undesired surface pollution in real‐world conditions and complex production methods that limit their possible application 58 …”

Facile fabrication of hierarchical textures for substrate-independent and durable superhydrophobic surfaces

“…18 In addition, superhydrophobic surfaces have important applications in nanogenerators, supercapacitors, chemical catalysis, etc . 20–23…”

A self-adaptive film for passive radiative cooling and solar heating regulation

“…[5][6][7][8] PDRC achieves Earth cooling by reecting solar light (l $0.3-2.5 mm) to minimize solar heat gain and emitting its own heat as an infrared radiation wave to ultracold outer space (3 K) through the atmosphere's longwave infrared (LWIR) transparency window (l $8-13 mm). [9][10][11] Our latest work presents a hierarchically structured polymethyl methacrylate lm with a dense micropore array and randomly distributed nanopores for efficient all-day subambient radiative cooling. 12 However, PDRC is only applicable for hot seasons/regions to reduce the cooling energy, but it poses an additional heating burden to offset the unwanted cooling on winter days, especially in highlatitude areas.…”
