Fig. 4: Structural change of GO/PG membrane in water and methanol.
From: Smart and solvent-switchable graphene-based membrane for graded molecular sieving
a XRD patterns of dry and wet (in methanol and water) GO membrane and GO/PG membrane. The diffraction peaks reflect the GO–GO nanochannel. b, c Free energy profiles of the swelling of the GO–PG nanochannel in water (b) and methanol (c). Inset: The d of GO–PG nanochannel swelled in methanol. The snapshots present the swollen GO–PG nanochannel from independent equilibrium MD simulations.
