a Temperature evolution curves of CNT-PCTRFs (25 cm2) by varying CNTs contents under 80 mW·cm-2 solar illumination. b η values of CNT-PCTRFs (25 cm2) at varying light intensities. c Radar chart comparing C22 and C22/CNT fibers in latent heat, mechanical properties, thermal conductivity, and η values. d Experimental setup for solar thermoelectric conversion. Temperature and output voltage of CNT2-PCTRFs under 100 mW·cm-2 (e) and variable solar intensities (f). g Schematic of PCM garment thermal regulation using C22/CNT2 fibers. h, i Photos, and mean temperature comparison between ordinary vests and PCM-based garments under solar exposure (h), and at high-temperature work environments (i), with wearing-time evolution, respectively. j1–m4 Infrared thermography images of ordinary vest (j1–j4, l1–l4), and thermoregulation PCM garment (k1–k4, m1–m4) under solar exposure and high-temperature conditions at increasing wearing times, respectively.
