Supported Lyotropic Liquid‐Crystal Polymer Membranes: Promising Materials for Molecular‐Size‐Selective Aqueous Nanofiltration

Abstract

The ordered monodisperse ionic channels existing in lyotropic 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.
