Photothermal ability and solar-driven vapor sorption–desorption properties of PZMGs. (A) Schematic illustration of the PZMG synthesis process. (Scale bar: 1 cm.) (B) UV–Vis–NIR spectra of PZMGs with varying Ppy contents, and the normalized spectral solar irradiance density of air mass 1.5 global (AM 1.5 G) tilt solar spectrum. Specifically, PZMG 1 to 4 corresponds to PZMG with 15 vol%, 10 vol%, 5 vol%, and 2 vol% of 0.1 g/mL Ppy:PSS solution. (C) Time-dependent surface temperature and the IR thermal images of PZMG-1 under different light intensities. (D) Water vapor sorption curve under 60% RH and desorption curve under 1 sun of PZMG-1, and sorption–desorption rates (green dots) of PAMG-1.
