  • Publication number: 20180147603
    Abstract: The material properties of structures made with conductive nanoparticles are enhanced by radiation sintering followed by chemical sintering. The conductive nanoparticles may be applied to substrates by methods such as screen printing, inkjet, aerosol and electrospinning and then sintering the conductive nanoparticles on the substrates.
    Type: Application

  • Patent number: 9801284
    Abstract: A method of manufacturing a patterned conductor is provided, comprising: providing a substrate, comprising: a base material with an electrically conductive layer disposed thereon; providing an electrically conductive layer etchant; providing a spinning material, comprising: a carrier; and, a photosensitive masking material; providing a developer; forming a plurality of masking fibers and depositing them onto the electrically conductive layer to form a plurality of deposited fibers; patterning the plurality of deposited fibers to provide a treated fiber portion and an untreated fiber portion; developing the plurality of deposited fibers, wherein either the treated fiber portion or the untreated fiber portion is removed, leaving a patterned fiber array; contacting the electrically conductive layer to the electrically conductive layer etchant, wherein the electrically conductive layer that is uncovered by the patterned fiber array is removed, leaving a patterned conductive network on the substrate.

  • Publication number: 20160152807
    Abstract: Flexible cable comprises a crosslinked insulation sheath made from a composition comprising in weight percent based on the weight of the composition; (A) 60-95% of an ethylene polymer of crystallinity of less than 40%; (B) 4 to less than 40% of a propylene polymer with an upper melting point of greater than or equal to (>)130° C.; and (C) >0.5% peroxide; with the proviso that the ethylene polymer either comprises a continuous matrix within which the propylene polymer is dispersed or is co-continuous with the propylene polymer. Compatibilizers are optional to the composition.

  • Publication number: 20140007940
    Abstract: Disclosed are thermoplastic resin formulations for use as a light transmitting layer (e.g., encapsulant layer) in a photovoltaic module comprising: (a) a light transmitting thermoplastic resin, (b) at least one down conversion material that exhibits a maximum in incident radiation absorption in the range of 280 to 500 nm and a maximum in radiation emission at a relatively longer wavelength in the range of 400 to 900 nm and improves the efficiency of photovoltaic electric current generation in a photovoltaic module; and (c) a light stabilizer additive that transmits at least about 40 percent of the ultraviolet (UV) electromagnetic radiation having a wavelength in the range of from about 280 nm to about 380 nm. Also disclosed are sheet materials prepared from such resins and photovoltaic modules incorporating such sheet materials.
