<p>Passive daytime radiative cooling materials have attracted increasing attention due to their great potential for energy</p><p>saving and the possibility to meet the need for smart clothes. However, the practical application of passive daytime cooling material in</p><p>the textile industry is greatly affected by comfort components and also physical/mechanical properties that require optimization. Herein,</p><p>it was aimed to develop a thermoregulating fabric using zinc oxide nanoparticles (ZnO), which provide dynamic and passive control of</p><p>the infrared transmission, by adapting to the ambient temperature. For this aim, the cotton fabric was coated with a nanocomposite</p><p>treatment composed of ZnO nanoparticles and temperature-responsive shape memory polyurethane (SMPU) matrix, obtaining strong</p><p>scattering effects to control the wideband transmission of thermal radiation and also adaptive comfort features based on shape memory</p><p>function. By reflecting sunlight of SMPU-ZnO nanocomposite coating, the cotton fabric can reach an average temperature drop of</p><p>2.2°C and 0.4°C compared to the raw ones under direct sunlight and also indoor at 40°C, respectively. Also, SMPU and SMPU-ZnO</p><p>nanocomposite coated cotton fabric exhibited dynamic air and water vapour permeability hence adaptive comfort features. Owing to</p><p>passive cooling and also adaptive comfort features besides the simple production process, this smart fabric is promising to be widely</p><p>used in sports or protective clothing areas.</p>
