  • Publication number: 20130119320
    Abstract: In a tumbler and the like, polypropylene pellets are blended with 1 to 5 wt. % of carbon nanotubes, 10 to 30 wt % of fly ash, 10 to 20 wt % of talc and 0.3 to 1 wt % of a modifier, the resulting blend is extruded from a screw extruder while heating the blend to a melting temperature of about 160 to 260° C., to generate a strand. This strand is cooled and cut into pellets having a predetermined length. Owing to blending with fly ash, talc and a modifier, an inexpensive lightweight electroconductive thermoplastic resin excellent in dust-proofness, heat resistance and recyclability is obtained, even if the blending amount of carbon nanotubes is small.

  • Publication number: 20130095384
    Abstract: A composite powder in which highly dispersed metal oxide nanoparticle precursors are supported on carbon is rapidly heated under nitrogen atmosphere, crystallization of metal oxide is allowed to progress, and highly dispersed metal oxide nanoparticles are supported by carbon. The metal oxide nanoparticle precursors and carbon nanoparticles supporting said precursors are prepared by a mechanochemical reaction that applies sheer stress and centrifugal force to a reactant in a rotating reactor. The rapid heating treatment in said nitrogen atmosphere is desirably heating to 400° C.-1000° C. By further crushing the heated composite, its aggregation is eliminated and the dispersity of metal oxide nanoparticles is made more uniform. Examples of a metal oxide that can be used are manganese oxide, lithium iron phosphate, and lithium titanate. Carbons that can be used are carbon nanofiber and Ketjen Black.

  • Publication number: 20120312467
    Abstract: The invention relates to a process for producing electrically conductive bonds between solar cells, in which an adhesive comprising electrically conductive particles is first transferred from a carrier to the substrate by irradiating the carrier with a laser, the adhesive transferred to the substrate is partly dried and/or cured to form an adhesive layer, in a further step the adhesive is bonded to an electrical connection, and finally the adhesive layer is cured. The invention further relates to an adhesive for performing the process, comprising 20 to 98% by weight of electrically conductive particles, 0.01 to 60% by weight of an organic binder component used as a matrix material, based in each case on the solids content of the adhesive, 0.005 to 20% by weight of absorbent based on the weight of the conductive particles in the adhesive, and 0 to 50% by weight of a dispersant and 1 to 20% by weight of solvent, based in each case on the total mass of the undried and uncured adhesive.
