Abstract:
... Lamellar membranes constructed from two-dimensional (2D) nanosheets have exhibited exceptional permselective characteristics. However, their complex and contaminative nanosheet synthesis, low structural stability, and low chemical resistance severely limit industrial-scale production and practical applications. Herein, the stability, molecular separation, ion-sieving properties, and broad applicab ...
