Supported lyotropic liquid-crystal polymer membranes: Promising materials for molecular-size-selective aqueous nanofiltration
The ordered monodisperse ionic channels existing in Iyotropic liquid-crystal (LLC) polymer films allow only the passage of water-soluble molecules which are smaller than the 1.2 nm diameter of the channels. When formed on an ultraporous polysulfone (PSf) support, the films are used effectively as size-selective sieves for water-soluble molecules. These membranes are able to completely reject molecules larger than their pore sizes.
