Membranes, Coatings and Films and Methods for Their Preparation

Abstract: There are provided herein selective membranes, such as composite membranes, and/or films and processes for their preparation. The membranes and/or films have a given morphology which may be stabilized, for example against swelling and chemical degradation, by covalent crosslinking and optionally, in addition, by hydrophobization. There is provided a membrane and/or film and a process for the preparation thereof, the membrane and/or film include an ionomer and/or polyelectrolyte crosslinked through aryl-aryl (-Ar-Ar-), aryl-ether-aryl (-Ar-O-Ar-) and/or aryl-sulfide-aryl (-Ar-S-Ar-) bonds.
