Core Viewpoint - Researchers from Cornell University have developed the darkest known textile fabric inspired by bird feathers, applicable to natural fibers like wool, silk, and cotton [2] Group 1: Material Properties - "Super black" materials are defined as substances with light reflectance below 0.5%, holding significant application value in fields such as camera lenses, solar panels, and astronomical telescopes [2] - The newly developed fabric maintains a stable black color that does not diminish with changes in observation angle, addressing common issues with existing super black materials [2] Group 2: Production Method - The team drew inspiration from the deep black color of the Violet-crowned Hummingbird's feathers, using polydopamine to dye white merino wool knit fabric and employing plasma etching to create nanostructures on the fiber surface [2] - The method is described as simple and easily scalable, allowing for widespread adoption in textile manufacturing [2] Group 3: Mechanism of Light Absorption - The deep black color of the bird's feathers is attributed to a rich concentration of melanin and tightly arranged barb structures, which enable light to be reflected internally and nearly completely absorbed [2] - The experimental approach involved using synthetic melanin as a dye and plasma etching to form spike-like nanofibers, enhancing light absorption through multiple reflections within the fibers [2]

Core Insights - The research team from Tianjin University has developed a new type of molecular solar thermal (MOST) fabric that can efficiently convert light into heat, achieving a surface temperature increase to 40°C within 12 seconds under -20°C conditions, and maintaining its thermal performance even after repeated washing and friction [1][5][6] - This innovation addresses the long-standing challenge of balancing mechanical and thermal management properties in personal thermal management fabrics, which is crucial for energy conservation and enhancing the convenience of medical therapies [1][5] Group 1: Research and Development - The MOST fabric is inspired by the salt-absorbing and salt-excreting mechanisms of the salt-tolerant plant "Kochia scoparia," which adapts to extreme environments through a dynamic cycle [5] - The team utilized thermoplastic polyurethane aerogel fibers as a substrate, which were treated with a special azobenzene/chloroform solution to create a dense crystalline layer on the fiber surface, enhancing both optical and mechanical properties [5][6] Group 2: Performance and Durability - Experimental results show that the new fabric can achieve a temperature increase of 25.5°C within 70 seconds under 420nm blue light, and 21.2°C within 50 seconds in simulated sunlight at -20°C [5] - The fabric exhibits exceptional durability, retaining over 90% of its thermal performance after 50 friction tests, 500 stretch-bend cycles, and 72 hours of continuous washing, overcoming the common issues of traditional MOST materials [5][6] Group 3: Applications and Future Prospects - The MOST fabric allows for precise control of heat release temperature by adjusting light intensity, making it suitable for everyday warmth and portable therapy applications for conditions like arthritis [6] - This biomimetic design not only provides a new method for large-scale production of MOST fabrics but also represents a breakthrough in thermal management fabric performance, with potential applications in smart clothing, medical therapy devices, and outdoor protective gear [6]
