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： The present disclosure provides a polymerizing method where (i) an ionic crosslinker that includes a quaternary ammonium group and (ii) a non-ionic crosslinker, is polymerized in a reaction solution whose solvent is substantially a mixture of propylene glyocol (PG) and an aprotic amide-based solvent. The polymerization makes an anion-exchange polymer composition. The PG and the aprotic amide-based solvent are present in a weight ratio of from about 25:75 to about 70:30, and the reactants and solvents are present in amounts to generate the anion-exchange polymer composition with a theoretical water content from about 35% to about 60% (wt/wt).
