Fig. 3: Construction of all-fiber e-textile with high thermal-moisture stability and comfortability.

a The e-textile exhibits good wearability which has the functions of breathability, moisture permeability and moisture wicking. b Schematic diagram of air permeability, moisture permeability of the e-textile. c Schematic diagram of the moisture wicking function of the e-textile in sweating state. From top to bottom, including skin, the moisture-wicking fabric (PAN-PA6-cotton fabric), conductive and dielectric fabric (fabric electrode-P(VDF-TrFE)-PA6). Air convection direction: green arrow. Liquid water transport direction: black dotted arrow. Water vapor transport direction: blue dotted arrow. Wettability gradient: the transition from light blue to dark blue indicates that the water content in the fiber layer changes from less to more. d Micrographs, contact angles of hydrophilic PAN and PA6 fibers. e Pore size distribution of hydrophilic PAN and PA6 fibers. f Water evaporation rate of cotton fabric, cotton-PAN fabric and cotton-PA6-PAN fabric (the moisture-wicking fabric). g Wetting behavior (ink droplets, 200 μL) of the moisture-wicking fabric from the top view.
