a UV–Vis–NIR spectrum of the solar absorber in the wet state, exhibiting a light absorptance of ~96%, in conjugation with the standard solar spectral irradiance (AM 1.5 G). b SEM image of GFM, showing the interwoven fibrous structure. c The blue curve illustrates the increase in capillary rise height of water within the GFM over time (see the recorded photos in Supplementary Fig. 2). The green curve depicts the linear escalation in the mass of water confined within the GFM, corresponding to the increase in capillary rise height. d Water sorption isotherm of the saturated LiCl solution.
