  • 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.
