  • Fibers made from soluble polymers
    Patent number: 11479882
    Abstract: A fiber can be made having a structure with an axial core and a coating layer. The fiber can have a polymer core and one or two layers surrounding the core. The fine fiber can be made from a polymer material and a resinous aldehyde composition such that the general structure of the fiber has a polymer core surrounded by at least a layer of the resinous aldehyde composition.

  • Conductive elastomeric foams and method of manufacture thereof
    Patent number: 7029722
    Abstract: A conductive polymer composite, comprising a polymer and polypyrrole and derivatives thereof. The composite is manufactured by first diffusing an oxidant such as iodine into the polymer, and then diffusing pyrrole or a pyrrole derivative vapor into the impregnated polymer, resulting in an in situ chemical oxidative polymerization of pyrrole at the oxidant site. The conductivity of the composite foam can be effectively controlled between 10?7 to 10?1 S/cm, inclusive.
