Abstract

Cette invention se rapporte au secteur de la chimie et concerne des membranes, telles que celles appliquées par exemple dans des piles à combustible directes au méthanol. L'objectif de cette invention est de produire des membranes, présentant une capacité de rétention du méthanol sensiblement améliorée. A cet effet, une membrane polymère pour piles à combustible présente une(des) couche(s) de séparation, au moins constituée(s) de copolymères deux- et/ou multi-blocs présentant les structures générales de segments A-(B-A)k et/ou B-(A-B)l et/ou (A-B)m avec k ≥ 1 et l ≥ 1 et m ≥ 1, le segment de bloc (A) étant constitué d'un segment oligomère non conducteur d'électrons et non conducteur de protons et le segment de bloc (B) étant constitué d'un segment oligomère conducteur de protons et non conducteur d'électrons. Cette invention concerne également un procédé consistant à mettre en réaction les substances de départ, afin de produire les segments de blocs (A) à partir d'au moins un segment oligomère non conducteur d'électrons et non conducteur de protons et les segments de blocs (B) à partir d'au moins un segment oligomère conducteur de protons et non conducteur d'électrons.
