Abstract
A functional membrane is provided for proton-driven ion transport. It consists essentially of a blend of two components. The first component is an active polymer having cation-binding sites, the cation binding sites being provided, e.g., by a crown ether, a cryptand or an acyclic complexone with an ionizable acidic site, e.g., a carboxylic acid, a sulfonic acid and a phenol, such active polymer being incorporated into a polymer backbone via a spacer component. The second component is a support polymer, e.g. a polyaramide, a polysulfone, or a polypip-erazine-fumaramide.
