  • Publication number: 20200219634
    Abstract: “A process is provided for preparing an electrically conductive composite film having at least one thermoplastic polymer resin and electrically conductive particles chosen from graphene, carbon nanotubes, carbon nano-fibres, and mixtures thereof; and filiform metal nanoparticles, the electrically conductive composite film optionally impregnating fibres. The process has a step of preparing a suspension comprising a solvent and electrically conductive particles chosen from graphene, carbon nanotubes, carbon nanofibres, and mixtures thereof; and filiform metal nanoparticles. The suspension has approximately from 0.06% to 0.5% by volume of the electrically conductive particles relative to the total volume of the suspension.

  • Publication number: 20170190856
    Abstract: A process is provided for preparing a high-performance composite part that is electrically conductive at the surface. The process is used for improving the resistance of an electrically insulating part to rubbing, wear, and harsh atmospheric and/or chemical conditions, and to ensure the protection of an electrically insulating part against electromagnetic radiation (electromagnetic shielding) and/or against electrostatic discharges. The process improves the surface electrical conductivity of a material.

  • Publication number: 20110168957
    Abstract: An electrically conductive solid composite material contains: a solid matrix of electrically insulating material, and—a load of an electrically conductive material, wherein the charge includes so-called filiform nanoparticles, having: a length, extending along a main elongation direction; two so-called orthogonal dimensions, extending along two directions which are transverse and orthogonal to each other and orthogonal to the main elongation direction, the orthogonal dimensions being less than the length and less than 500 nm; and two so-called form factor ratios between the length and each of the two orthogonal dimensions, the form factor ratios being greater than 50, the filiform nanoparticles being distributed within the volume of the solid matrix with an amount, by volume, of less than 10%, particularly less than 5%.
