  • CAST FILMS AND EXTRUSION-COATED SUBSTRATES CONTAINING NANOCOMPOSITE AND COMPATIBILIZER
    Publication number: 20250256447
    Abstract: Disclosed are cast films and extrusion-coated substrates, and their methods of making. The cast films and coatings on the substrates are made from a composition containing an ungrafted ethylene-based polymer, a nanocomposite containing a polyamide and montmorillonite, and a compatibilizer comprising a maleic anhydride grafted ethylene-based polymer. These films and coatings can have improved optical and/or mechanical properties compared to films and coatings made without the nanocomposite.

  • Thermoplastic polyurethane graphene oxide nanocomposites with enhanced mechanical behavior
    Patent number: 10793695
    Abstract: A polymer nanocomposite composition, wherein nanoparticles, preferably graphene oxide, are well dispersed within a polymer matrix, preferably thermoplastic polyurethane in one embodiment. Affinity of the nanoparticles to one of the phases of the polymer matrix, preferably a hard segment of the thermoplastic polyurethane, provides enhanced mechanical properties. Processes for preparing the polymer nanocomposite compositions are described. In a preferred embodiment, an extensional dispersing element is included within the screw configuration of an extrusion process.
