Nicole Hildebrandt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Porous film material comprising at least one carbonaceous semimetal oxide phase, and use thereof as a separator material for electrochemical cells
    Patent number: 8603681
    Abstract: The present invention relates to a novel porous film material which comprises at least one carbonaceous semimetal oxide phase, and to a process for production thereof. The invention also relates to the use of these porous film materials as a separator layer or for production of such separator layers in electrochemical cells, particularly in lithium cells and especially in lithium secondary cells.

  • TRANSPARENT SEMI-INTERPENETRATING NETWORK COMPRISING A PHASE OF A LINEAR, NON-CROSSLINKED ISOBUTENE POLYMER
    Publication number: 20110230621
    Abstract: A transparent, semi-interpenetrating network comprises a first phase of a linear noncrosslinked isobutene polymer and a second phase of a crosslinked polymer. The crosslinked polymer is obtained through copolymerization of a first ethylenically unsaturated monomer and of a second ethylenically unsaturated monomer, wherein the first ethylenically unsaturated monomer is a cycloalkyl(meth)acrylate and the second ethylenically unsaturated monomer is selected from linear and branched C1-C20 alkyl(meth)acrylates. By varying the ratio of the first ethylenically unsaturated monomer relative to the second ethylenically unsaturated monomer, the properties, such as vibration damping properties, of the semi-interpenetrating network can be controlled.

  • SEMI-INTERPENETRATING NETWORK HAVING A PHASE OF A LINEAR NONCROSSLINKED ISOBUTENE POLYMER
    Publication number: 20100170636
    Abstract: A description is given of a semi-interpenetrating network having a first phase of a linear noncrosslinked isobutene polymer and a second phase of a crosslinked polymer, wherein the crosslinked polymer is obtained by crosslinking molecular enlargement reaction in the presence of the isobutene polymer. The crosslinked polymer is preferably obtained by free-radical polymerization of ethylenically unsaturated monomers comprising at least one polyethylenically unsaturated monomer. The networks are suitable as molding compounds having gas and moisture barrier effect or as adhesives.
