  • CONDUCTIVE COMPOSITE MATERIAL CONTAINING A THERMOPLASTIC POLYMER AND CARBON NANOTUBES
    Publication number: 20130009110
    Abstract: Methods for controlling and improving the conductivity of thermoplastic polymer composites containing CNTs or even for making these materials conductive when they are initially insulating. For example, methods including either injection moulding or extrusion at a temperature above the melting temperature of the polymer, or a subsequent heat treatment step of said composite obtained by injection moulding or extrusion.

  • Multi-layer polyelectrolyte membrane
    Patent number: 8039160
    Abstract: Multi-layer polyelectrolyte membranes are described wherein at least one of the layers contains at least one acrylic resin or vinyl resin having at least one ionic or ionizable group, and at least one additional polymer. The polymer has small or large domain sizes with respect to the acrylic resin or vinyl resin that is present in one or more layers. The polymer preferably has improved conductivity when formed into a film. The membranes are useful in batteries, fuel cells, and the like.

  • METHOD FOR PREPARING A THERMOPLASTIC COMPOSITE MATERIAL CONTAINING NANOTUBES PARTICULARLY CARBON NANOTUBES
    Publication number: 20110201731
    Abstract: One subject of the present invention is a method for preparing a composite preferably containing 10 to 50% by weight of nanotubes, comprising: (a) the introduction, into a mixer, of nanotubes and at least one thermoplastic polymer, such as a homopolyamide or copolyamide, a polycarbonate, SBM or a PEG; (b) the melting of the thermoplastic polymer; and (c) the mixing of the molten thermoplastic polymer and the nanotubes, provided that aplasticizer is introduced upstream of, or in, the melting zone of the polymer. The invention also relates to the composite thus obtained and to its use in the manufacture of a composite product.
