(EN) ION EXCHANGE MEMBRANE AND METHOD OF MANUFACTURING AN ION EXCHANGE MEMBRANE
(FR) MEMBRANE ÉCHANGEUSE D’IONS ET PROCÉDÉ DE FABRICATION D’UNE MEMBRANE ÉCHANGEUSE D’IONS
Abstract
(EN)
This invention relates to an an-ion exchange membrane and method for making said membrane. The membrane being intended for use in electrolysers or other AEM electrochemical devices. The membrane comprises: a thermoplastic elastomer (TPE) comprising styrene, said TPE being a polymeric backbone, wherein: the styrene content of the thermoplastic elastomer is between 30wt% and 70wt%, and crosslinking of a first polymeric backbone to one or more other polymeric backbones, and one or more cationic groups, and the functionalisation degree is between 1% and 50%.

La présente invention concerne une membrane échangeuse d’anions et un procédé de fabrication de ladite membrane. La membrane est destinée à être utilisée dans des électrolyseurs ou d’autres dispositifs électrochimiques AEM. La membrane comprend : un élastomère thermoplastique (ETP) comprenant du styrène, ledit ETP étant un squelette polymère. La teneur en styrène de l’élastomère thermoplastique est comprise entre 30 % en poids et 70 % en poids, et la réticulation d’un premier squelette polymère à un ou plusieurs autres squelettes polymères, et un ou plusieurs groupes cationiques ; le degré de fonctionnalisation est compris entre 1 % et 50 %.
