Simulation and fabrication of radiative heating textile. a Simulated set-points of ambient temperature for maintaining thermal comfort as a function of the textile’s IR emissivity at the inner surface (ε i) and outer surface (ε o). Schematics depicting the heat dissipation and vapor transmission of human body covered with b traditional textile and c nanophotonic structure heating textile composed of an IR-transparent layer and an IR-reflective layer with embedded nanopores in both layers to simultaneously achieve minimal IR emissivity and good breathability. d Simulated total IR reflectance of metallic nano-island film and metallic nano-mesh film with coverage density of 81%. The island size is 900 nm × 900 nm. The hole size is 440 × 440 nm. For both cases, the period is 1 µm × 1 µm. e Schematic representation of the fabrication process of nano-Ag/PE textile, which is laminated on the outer surface of cotton. f Photos and SEM images of the Ag side and PE side of nano-Ag/PE.
