Copper sulfide and polyelectrolyte decorated textiles for active/passive personal thermal management.

[Display omitted] • A versatile coating was fabricated based on an electrostatic-coordination strategy. • The textile exhibited excellent solar/Joule heating performances properties. • The textile presented passive radiative heating properties. • The textile could protect the human body effectively in practical environments. • The research brought new insights into the development of PTM devices. The development of multifunctional textile-based personal thermal management devices is a prospective option for accurately warming the human body while effectively reducing energy consumption. However, existing multifunctional thermal management devices still face challenges in terms of high-performance integration. Here, we proposed an electrostatic-coordination-based strategy to fabricate successfully a versatile textile for body warming via sequentially covering cotton fiber with bio-based polyelectrolyte and in-situ grown copper sulfide coatings. The textiles with excellent solar/Joule heating properties and reduced infrared emissivity can efficiently heat the body in various environments and suppress thermal radiation dissipation from the body to the environment. Also, the textile realizes high-performance integration of electromagnetic shielding, UV protection, antimicrobial, and flame-retardant properties. This universal and efficient strategy provides a promising solution for the manufacture of all-day and energy-saving versatile personal thermal management devices, showing great potential for practical applications.
