  • Conductive fibers
    Patent number: 5593618
    Abstract: The present invention relates to a method for increasing the electrical conductivity of a polymeric substrate material, characterized by treating said material with an intermediate composition having an affinity for the material, said intermediate composition containing a grouping capable of forming a complex or otherwise reacting with a transition metal ion, forming such complex or reaction product with said transition metal ion, and combining said metal ion with an anion moiety thereby increasing the conductivity of said material.
    Type: Grant
    Filed: March 7, 1995
    Date of Patent: January 14, 1997
    Assignee: Instytut Wlokiennictwa
    Inventors: Marian K. Okoniewski, Jerzy S. Szadowski, Piotr J. Bajda, Jerzy Z. Kobus, Joanna Koprowska, Barbara E. Ratajczyk
