a Schematic of the SAG film composed of SA chains, SiO2 nanofiber, and rGO nanosheet. b Scanning electron microscopic (SEM) image of SAG film. Inset is the photograph of flexible SAG film. c Photos of SAG film in water during stirring (200 rpm) before and after 5 days. d Moisture adsorption and desorption kinetics for SAG film at 40oC. e Mt/Me and (Xt−Xe)/(X0−Xe) as a function of square root of time. f Adsorption and desorption diffusion coefficient of SAG film under different RH at 40oC. g Zeta potential of SAG film within the pH range from 3 to 8. h 23Na solid state NMR spectra of SAG film with various water content. i The electrochemical impedance spectra of SAG film at 100% RH.
