摘要： An ion-exchange membrane is disclosed here including ion-permeable layers impregnated with an ion-exchange material and arranged in an order from one face of the membrane to the opposite face of the membrane such that opposing layers in the supporting membrane substrate provide sufficiently identical physical properties to substantially avoid irregular expansion when in a salt solution. The ion-permeable layers including at least one non-woven layer and at least one reinforcing layer.

摘要： An ion exchange membrane and a method of making it. The membrane may be used, for example, in an electrodialysis module or electrochemical cell. The membrane comprises an ion exchange polymer and inorganic particles preferably linked to the ion exchange polymer. To make a membrane, inorganic particles are mixed into an ion exchange membrane pre-cursor. A polymerization initiator or catalyst is then added and the resulting mixture is placed in a form and cured. The inorganic particles may comprise, for example, an oxidized form of graphite such as graphite oxide. The ion exchange polymer may comprise an ionic monomer, containing a quaternary ammonium group for anion exchange or a sulfonate group for cation exchange, along with a crosslinking co-monomer containing polymerizable diacrylic functionalities. The membrane is self-supporting and can be made without a supporting fabric.

摘要： Acid block anionic selective polymeric membranes are provided of the type having a woven or non-woven cloth reinforcing structure. The polymer of the membrane is prepared by the process comprising copolymerizing components I, II, and III wherein I is an ethylenically unsaturated aliphatic or aromatic tertiary or quaternary amine monomer. II is a cross-linking monomer, and III is vinylbenzyl chloride. The reaction is conducted in the presence of a free radical polymerization initiator. Additionally, anionic exchange membranes of the type used in electrodialysis apparatus are disclosed and comprise a woven or nonwoven cloth that is impregnated with a copolymer comprising the reaction products of components I, II, and III.
