  • Use of a functionalized mineral filler for chemically stabilizing a polymer, membrane thus stabilized, process for preparing same and uses thereof
    Patent number: 9211505
    Abstract: 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.
    Type: Grant

  • Nanoporous laminates
    Patent number: 7485362
    Abstract: 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.
