  • Publication number: 20130190442
    Abstract: The linear low density polyethylene nanocomposite fibers are formed from a linear low density polyethylene matrix having carbon nanotubes embedded therein. The addition of the carbon nanotubes enhances the overall toughness of the material, resulting in increases over conventional linear low density polyethylene in the material's tensile strength, elasticity and ductility. The carbon nanotubes constitute between about 0.08% and 1.0% by weight of the linear low density polyethylene nanocomposite fiber. Optimal toughness is found at about 0.3 wt %. The linear low density polyethylene nanocomposite fibers are made by first melting a quantity of linear low density polyethylene, and then blending a quantity of carbon nanotubes into the melted linear low density polyethylene to form a mixture, The mixture is then extruded to form the linear low density polyethylene nanocomposite fibers, which are then spun in a spinneret die to produce the finished linear low density polyethylene nanocomposite fibers.

  • Patent number: 8399551
    Abstract: An embodiment of the present invention is a nanocomposite comprising a clay and an elastomer comprising at least C2 to C10 olefin derived units; wherein the elastomer also comprises functionalized monomer units pendant to the elastomer. Desirable embodiments of the elastomer include poly(isobutylene-co-p-alkylstyrene) elastomers and poly(isobutylene-co-isoprene) elastomers, which are functionalized by reacting free radical generating agents and unsaturated carboxylic acids, unsaturated esters, unsaturated imides, and the like, with the elastomer. The clay is exfoliated in one embodiment by the addition of exfoliating agents such as alkyl amines and silanes to the clay. The composition can include secondary rubbers such as general purpose rubbers, and curatives, fillers, and the like. The nanocomposites of the invention have improved air barrier properties such as are useful for tire innerliners and innertubes.
