(A) Schematic of the experimental setup for monitoring fluid transmembrane transport.

(B) The multilayer assembly of the GO/SNF/GO membrane.

(C) SEM image evidencing the sandwich-like architecture of the composite membrane mimicking nacre, scale bar is 200 nm.

(D) XRD measurements for estimating the change in interlayer spacing d.

(E) GO/SNF/GO composite structures constructed by amphiphilicity-driven assembly, scale bar is 500 nm.

(F) FTIR spectra acquired from the GO membrane, SNFs, and GO/SNF/GO membrane.

(G) Stress−strain curves of GO and GO/SNF/GO membranes with different SNF contents.

(H) Toughness-mass ratio of SNF curves of different membranes.
