The present invention relates to a membrane that includes a porous polymer material made of a polyimide with interconnected macropores and impregnated with protic ionic liquid conductors (CLIP), as well as to the method for manufacturing same and to the uses thereof. The membranes of the invention fulfill the need for membranes including CLIPs, which have good proton-conducting properties as well as good physical properties, in particular high thermal and mechanical stability, in addition to a wide range of electrochemical stability.

Proton-conducting composite membrane for fuel cells

The present invention concerns the use of at least one mineral filler functionalized by at least one group comprising at least one sulfur atom for chemically stabilizing a polymer matrix and/or for increasing the durability thereof. The present invention also concerns a membrane such as an ion exchange membrane and in particular a proton exchange membrane thus stabilized, its method of preparation and uses thereof.

Use of a functionalized mineral filler for chemically stabilizing a polymer, membrane thus stabilized, process for preparing same and uses thereof

The invention relates to a process for the extrusion of thermoplastic polymers having alkaline ionic groups. The process consists in preparing a mixture composed of a thermoplastic polymer having alkaline ionic groups and a plasticizer, in extruding the mixture obtained to form a film; then in washing the film obtained in aqueous medium to remove said plasticizer(s). The plasticizer is chosen from non-volatile compounds which are stable with respect to the ionic groups of the polymer, which are soluble in water or in solvents that are miscible with water, said plasticizers being chosen from the compounds that react with the ionic group of the polymer via formation of a weak bond of the hydrogen bond-type, and the compounds that react with the ionic group of the polymer via formation of a strong bond, of the ionic bond-type.

The present invention relates to polymers comprising phenylene units, at least one of which bears a phenylene side group substituted with a perfluoro group or chain, which itself bears an &#x2014;SOH, &#x2014;POHor &#x2014;COH group. Use of this polymer to make fuel cell membranes.

Polyphenylene-type polymers, preparation method thereof, membranes and fuel cell device comprising said membranes

A process of making a nanoporous substrate, such as the matrix in an electrical laminate, by grafting onto an organic resin backbone a thermolabile functionality by reacting hydrogen active groups of the organic resin with a compound containing thermolabile groups; then thermally degrading the thermolabile groups grafted on the organic resin to form a nanoporous laminate. Advantageously, the nanoporous electrical laminate has a low dielectric constant (Dk) because of the nanopores present in the laminate matrix.
