    Abstract: Reduction/oxidation reagents have been found to be effective to chemically cure a sparse metal nanowire film into a fused metal nanostructured network through evidently a ripening type process. The resulting fused network can provide desirable low sheet resistances while maintaining good optical transparency. The transparent conductive films can be effectively applied as a single conductive ink or through sequential forming of a metal nanowire film with the subsequent addition of a fusing agent. The fused metal nanowire films can be effectively patterned, and the patterned films can be useful in devices, such as touch sensors.

  • Publication number: 20040142620
    Abstract: The present invention relates to a nonwoven web comprised of metal or refractory fibers with poly(phenylene sulfide) as a binder. The nonwoven web is prepared by forming a foam furnish by agitating the fibers in a foamed medium, and passing the foam furnish onto a screen and defoaming the furnish. It is preferred that the poly(phenylene sulfide) binder is added to the foam furnish in the form of fibers. Once the furnish is defoamed to form a nonwoven web, the sheet is heated at a temperature sufficient to melt the poly(phenylene sulfide) binder.

  • Patent number: 6730622
    Abstract: An electrical cable of the present invention comprises a plurality of spaced, parallel flat conductors. Each of the plurality of flat conductors was previously integral with each immediately adjacent flat conductor. A dielectric material is holds the conductors in the spaced, parallel relationship. The dielectric material can be a polymer film, a nonwoven, or other polymer materials such as PTFE, or expanded PTFE. The cable of the present invention is made by providing first and second webs of dielectric materials and a third sheet of conductive material. The first and second web materials are bonded to the third sheet of conductive material in a face-to-face layered relationship thereby forming a bonded laminate. The bonded laminate is then incrementally stretched to separate the sheet of conductive material in to spaced, parallel flat conductors.

    Abstract: Methods and systems for selectively connecting and disconnecting conductors in a fabric are disclosed. First and second conductors are integrated into a fabric such that the conductors intersect at a crossover point. The conductors are bonded to each other at the crossover point to improve AC and DC characteristics. Disconnect areas may be provided near the crossover point to allow selective disconnection of the conductors from the crossover point.
