  • 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.
    Type: Grant
    Filed: December 20, 2004
    Date of Patent: February 3, 2009
    Assignee: Dow Global Technologies Inc.
    Inventors: Ludovic L. Valette, Catherine Marestin, Regis Mercier
