Abstract

Given the increased extreme weather events and grown pressures on global energy consumption, there is an urgent need for personal thermal management (PTM) textiles with adaptive capabilities to enhance all-weather comfort. However, developing bidirectional PTM textiles with both cooling and heat preservation capabilities remains a significant challenge. Herein, a multifunctional colored photonic crystal (MCPC) textile is conducted by combining an emission-enhanced amorphous photonic crystals (APCs) layer and a low-emission MXene layer. The distinct solar reflection and infrared emission properties of the APCs and MXene layers impart precise thermal regulation. In cooling mode, MCPC achieves high solar reflectance (78.85 %) and infrared emittance (92.03 %), reducing temperature by 10.2 °C compared to bare skin. In heating mode, its high solar absorption (80.33 %), low emissivity (18.24 %), and electric heating raise the temperature by 21.4 °C. This work offers a practical solution for year-round thermal management, demonstrating substantial potential for energy-saving applications in all-weather smart clothing.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
