  • Polymer formulation for coating a metal core
    Patent number: 12376494
    Abstract: Multicomponent fibers with a piezoelectric effect, including an electroactive fluoropolymer shell which adheres to a metal core. Also, a solvent-based fluoropolymer formulation which makes it possible to obtain optimum adhesion to a bare, electrically conductive metal filament. Also, a process for manufacturing these composite fibers, and also their uses in varied sectors of technical textiles, filtration and in electronics.
    Type: Grant
    Filed: December 11, 2019
    Date of Patent: July 29, 2025
    Assignee: ARKEMA FRANCE
    Inventors: Fabrice Domingues Dos Santos, Simon Jestin
  • Method for producing a carbon fibre by recycling cotton
    Patent number: 11578433
    Abstract: The invention concerns a method for producing a carbon fibre, that comprises a step of preparing a continuous fibre made of cellulose from cotton fabrics, by extracting, from these fabrics, cotton in the form of short, discontinuous fibres, and implementing a solvent spinning process; this step being followed by a step of carbonising said obtained continuous fibre made from cellulose, in order to form a carbon fibre. This carbon fibre can be used, in particular, for producing articles made from composite material made from carbon fibres and polymer organic resin.
