Porous Membranes Thin semi-permeable membranes are commonly used as chemical barriers or for filtration purposes. While the size of the pores will influence which molecules are able to pass, other factors—including the surface chemistry of the pore walls, electrostatic interactions, and differences in solubility—can also affect the diffusion rates. There is also a trade-off between the thickness of the membrane regarding strength and permeation rates (see the Perspective by Paul). Karan et al… 

Precise and Ultrafast Molecular Sieving Through Graphene Oxide Membranes

This work investigates permeation through micrometer-thick laminates prepared by means of vacuum filtration of graphene oxide suspensions, which reveal that the GO membrane can attract a high concentration of small ions into the membrane, which may explain the fast ion transport.

Electrically controlled water permeation through graphene oxide membranes

Elect electrically controlled water permeation through micrometre-thick graphene oxide membranes is demonstrated, from ultrafast permeation to complete blocking, which opens up an avenue for developing smart membrane technologies for artificial biological systems, tissue engineering and filtration.

Graphene-based membranes for organic solvent nanofiltration

Different from the conventional polymeric separation membranes having a wide flexible-pore size distribution, layered graphene-based films with interconnected nanochannels provide narrowly

Selective Gas Transport Through Few-Layered Graphene and Graphene Oxide Membranes

It is demonstrated that few- and several-layered graphene and graphene oxide (GO) sheets can be engineered to exhibit the desired gas separation characteristics, and tunable gas transport behavior was strongly dependent on the degree of interlocking within the GO stacking structure.

Knudsen effusion through polymer-coated three-layer porous graphene membranes

The results suggest that the permeable pores created in three layer graphene were larger than those required for molecular sieved and that designs based on single layer graphene may lend themselves more easily to molecular sieving of gases.

Selective molecular sieving through porous graphene.

It is shown that ultraviolet-induced oxidative etching can create pores in micrometre-sized graphene membranes, and the resulting membranes can be used as molecular sieves and agree with models based on effusion through a small number of ångstrom-sized pores.

Molecular simulation of permeation behaviour of ethanol/water molecules with single-layer graphene oxide membranes

Abstract Graphene oxide (GO)-based materials have shown promise as water-permeating membranes in pervaporation separation. However, the feed permeation and surface affinity of single-layer nanoporous

Mechanisms of gas permeation through single layer graphene membranes.

Analytical expressions are derived for gas permeation through such atomically thin membranes in various limits of gas diffusion, surface adsorption, or pore translocation as the rate-limiting step.
