Nanoporous membrane used in filter, comprises two-dimensional material permeated by pores which are blocked by polymer derived from monomer and comprising population of pores having average pore diameter.

KIDAMBI P R, CHENG P

Multi-layered membrane useful for separating many ions or molecules in a fluid stream and in device for osmotic power generation, comprises a top layer, a bottom layer, and a spacer layer.

GARAJ S, SPINA M

Membrane useful for e.g. water filtration, water desalination, immune-isolation, hemodialysis and hemofiltration, comprises first layer and second layer comprising porous graphene-based material, channel, and at least one spacer substance.

SWETT J L, SIMON S M, BEDWORTH P V

Membrane used for e.g. dehydrating unprocessed fluid, comprises porous substrate, and graphene oxide layer comprising optionally substituted crosslinked graphene oxide comprising graphene oxide and crosslinkage which is diaminobenzene.

ZHENG S, KITAHARA I, KOBUKE M, WANG P, BARTELS C R, YAMASHIRO Y, HIROSE M, NOUMI S, LIN W, OOU M

Composite nanostructure useful in a filtration membrane e.g. microfiltration membrane for filtering a liquid i.e. water, comprises a graphene oxide shell, and a nanoparticle i.e. titanium dioxide or silver within the shell.

FORTNER J, BISWAS P, JIANG Y, WANG W

Formation of membrane for e.g. separating water from water/oil emulsion, involves dispersing graphene oxide nanoparticles in solvent, depositing graphene oxide nanoparticles on support, and reducing obtained graphene oxide membrane.

YU M

Deionizing fluid carrying unwanted ions involves applying pressurized fluid to first surface of perforated graphene in cylindrical form, so that fluid flows to second side of the sheet in preference to ions; and collecting the fluid.
