Abstract
Interpenetrating polymer networks comprising a first network of polymer A formed from monomers, at least one of which contains an aromatic group functionalized with a cation-exchange group, and a second network of polymer B formed from monomers, at least one of which contains a fluorinated group (RF). Use of these interpenetrating polymer networks for manufacturing fuel cell membranes.
