Harnessing Infrared Radiation with MXene Spray Coating for Temperature Control
Researchers at Drexel University have discovered that a thin coating of MXene, a two-dimensional nanomaterial, can enhance a material's ability to trap or shed heat by regulating the passage of ambient infrared radiation. MXene coatings can be used for both localized thermal management and large-scale radiative heating and cooling systems. MXene-coated textiles can reflect external infrared radiation to avoid heating from sunlight while allowing the infrared radiation emitted from the body to pass, making them more effective than passive cooling materials available in the market today. MXenes could be integrated into lightweight clothing that keeps the wearer warm in extreme environments.
