a XRD patterns of pure MoS2 and MoS2-PDDA membranes in the wet state. b–c GISAXS images of pure MoS2 (b) and MoS2-PDDA (c) membranes. d Schematic illustration of the developed channel in pure MoS2 and MoS2-PDDA membranes. e XRD patterns of MoS2-PDDA membranes in various aqueous media. f Evolution of the interlayer d-spacing of the MoS2-PDDA membrane at varied pH levels represented by pure water, 0.01 M HCl, and 1 M H2SO4 over an extended period of immersion. g Comparison of the swelling percentage between the MoS2-PDDA membrane and other 2D membranes reported in the literature. Note that, unless otherwise specified, the PDDA content in MoS2-PDDA membranes is 12.0 wt.%.
