我国科学家研发仿生光热织物 既可秒升温又稳定耐用

Core Insights - The research team from Tianjin University has developed a new type of molecular solar thermal (MOST) fabric inspired by the salt-absorbing mechanisms of salt-tolerant plants, which could revolutionize wearable thermal management technology [1][4]. Group 1: Technology Development - The new MOST fabric can rapidly increase its surface temperature to 40°C within 12 seconds under -20°C conditions, demonstrating significant thermal management capabilities [1]. - The fabric maintains over 90% of its thermal performance even after 50 friction tests, 500 stretch-bend cycles, and 72 hours of continuous washing, addressing durability issues faced by traditional MOST materials [4][5]. Group 2: Mechanism and Materials - The design utilizes thermoplastic polyurethane aerogel fibers as a base, which are treated with a special azo-benzene/chloroform solution to create a dense crystal layer that enhances optical and mechanical properties [4]. - The fabric can precisely control heat release temperature by adjusting light intensity, making it suitable for both daily warmth and therapeutic applications for conditions like arthritis [5]. Group 3: Market Applications - This innovative fabric has potential applications in smart clothing, medical therapy devices, and outdoor protective gear, marking a shift from reliance on external energy sources to efficient solar energy utilization [5][6].
