Tunability of IR radiation property and versatile choices of low-cost metals. a SEM images of the electrolessly plated Ag film with varying plating time from 10 to 50 min. Scale bar, 1 µm. b IR emittance spectra of the cotton/Ag/PE textiles with different Ag plating time. c Plots of the average IR emissivity (normalized over human body radiation) and the measured set-point of ambient temperature vs. the Ag plating time. d Measured IR emittance of the cotton/Cu/PE and cotton/Ni/PE textile samples. e Comparison of the set-points for bare skin, cotton, cotton/Cu/PE and cotton/Ni/PE. All error bars represent the standard deviation
