Cellulose acetate hierarchical porous coated textile with passive daytime radiative cooling, flexibility and durability
Passive daytime radiative cooling technology is a highly efficient cooling technology with zero energy consumption. When utilized for personal thermal management, radiative cooling textiles are capable of finely regulating the temperature of the human skin microenvironment. This study presents a cellulose acetate (CA) hierarchical porous coated textile that accomplishes high reflectance of sunlight over the full wavelength range, with a low cost and scalability, and a simple preparation procedure. With a high reflectance of 0.91 in the solar wavelength band and a high emissivity of 0.95 in the atmospheric window wavelength band, the CA hierarchical porous coated textile offers exceptional spectrally selective performances. It manifests a subambient cooling temperature of up to 19.0 °C and a skin overheating prevention effect of up to 4.2 °C. Furthermore, the coated textile possesses promising abrasion resistance, acid-alkali corrosion resistance, and mechanical properties. The present work provides a facile path for the development of green-based radiative cooling coated textiles.
期刊介绍：
The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as:
• Chemical, physical and technological properties of organic coatings and related materials
• Problems and methods of preparation, manufacture and application of these materials
• Performance, testing and analysis.
