外文摘要：Asymmetric surface modified polyester/cotton fabric (Janus T/C fabric) which exhibits remarkable temperature-adaptive personal moisture and thermal managements. Janus T/C fabric was created by combining two distinct temperature-sensitive hydrophobic/hydrophilic transition materials through single-sided spraying coating technique and in-situ ultraviolet-induced free radical polymerization. The base material for the Janus T/C fabric was 60/40 polyester/cotton blend fabric (T/C fabric). 2-(2-methoxyethoxy) ethoxyethyl-methacrylate (MEO2MA) and N, N-dimethyl (methacryloylethyl) ammonium propane sulfonate (DMAPS) were selected as thermoresponsive monomers. MEO2MA was used to create lower critical solution temperature (LCST) polymer, while DMAPS produced an upper critical solution temperature (UCST) on T/C fabric surface. The morphology, moisture permeability and thermal management capabilities of the Janus T/C fabric were investigated. The surface of Janus T/C fabric exhibited a reversible transition in hydrophobicity/hydrophilicity in response to variations in environmental temperature. Specifically, when the temperature exceeded the LCST, the fabric’s surface became hydrophobic, while below the LCST, it turned hydrophilic. Conversely, above the UCST, the fabric’s surface became hydrophilic, and below the UCST, it reverted to hydrophobic. The Janus T/C fabric with its distinct hydrophobic and hydrophilic surfaces, exhibited a remarkable wettability gradient. This wettability gradient was responsible for significantly increased moisture permeability, reaching 6792.5 g/m2·24h—surpassing the 60/40 T/C fabric by 1132.1 g/m2·24h at 40 °C. Furthermore, the Janus T/C fabric offered practical benefits in temperature adaptation. In hot environments, it provided a cooling effect of approximately 1.2 °C, while in cold conditions, it delivered a warming effect of approximately 1.0 °C. These thermoresponsive properties of asymmetric surface modified polyester/cotton fabric make it as an ideal choice for personalized moisture and thermal management, ensuring optimal comfort across varying temperatures. ? 2024, The Authors.
