Patent

CA 2214122

A composite membrane is provided which includes a base material and an ion exchange resin. The base material has a microstructure characterized by nodes interconnected by fibrils, or a microstructure characterized by fibrils with no nodes present. The ion exchange resin substantially impregnates the membrane such that the membrane is essentially air impermeable.

L'invention concerne une membrane composite comprenant un matériau support et une résine échangeuse d'ions. Le matériau de base a une microstructure qui se caractérise par des noeuds reliés entre eux au moyen de fibrilles, ou bien une microstructure qui se caractérise par des fibrilles sans noeuds. La résine échangeuse d'ions imprègne sensiblement la membrane, si bien que ladite membrane est sensiblement imperméable à l'air.
