  • Electrospinning ultrafine conductive polymeric fibers
    Patent number: 7264762
    Abstract: A process of making conductive polymeric fibers by electrospinning fibers from a blend of polymers dissolved in an organic solvent includes generating a high voltage electric field between oppositely charged polymer fluid in a glass syringe (4) with a capillary tip (5) and a metallic collection screen (2) and causing a polymer jet (3) to flow to the screen (2) as solvent evaporates and collecting fibers on the screen (2).

  • Chiral polyanilines and the synthesis thereof
    Patent number: 6090985
    Abstract: The present invention generally describes novel chiral polyanilines in their doped (protonated) forms and novel methods for their chemical synthesis comprising polymerizing an aniline monomer in the presence of a chiral dopant acid, an oxidizing agent, and, optionally, a substrate, and their conversion by treatment with a base to novel chiral polyanilines in their de-doped base forms. The novel chiral polyanilines of the present invention may be used as electrodes for asymmetric synthesis, as biological sensors and as separation materials in pharmaceutical applications.
