  • Patent number: 9238724
    Abstract: A method of producing an elastomer composite. The method includes A) combining a first fluid comprising elastomer latex with a second fluid comprising particulate filler; B) causing the elastomer latex to coagulate, thereby forming masterbatch crumb; C) bringing the masterbatch crumb to a water content of about 1 weight percent to about 20 weight percent, thereby forming a de-watered coagulum; D) removing water from the de-watered coagulum by subjecting the dewatered coagulum to mechanical energy, thereby causing the dewatered coagulum to heat as a result of friction, while allowing the dewatered coagulum to achieve a temperature of about 130° C. to about 190° C., wherein water content is reduced to about 0.5% to about 3% and wherein substantially all of the decrease in water content is accomplished by evaporation, thereby producing a masticated masterbatch; and E) subjecting the masticated masterbatch to at least an additional 0.3 MJ/kg of mechanical energy while further reducing the water content.

  • Patent number: 9157003
    Abstract: New methods for preparing carbon nanotube films having enhanced properties are provided. The method broadly provides reacting carbon nanotubes (CNTs) and compounds comprising a polyaromatic moieties in the presence a strong acid. During the reaction process, the polyaromatic moieties noncovalently bond with the carbon nanotubes. Additionally, the functionalizing moieties are further functionalized by the strong acid. This dual functionalization allows the CNTs to be dispersed at concentrations greater than 0.5 g/L in solution without damaging their desirable electronic and physical properties. The resulting solutions are stable on the shelf for months without observable bundling, and can be incorporated into solutions for printing conductive traces by a variety of means, including inkjet, screen, flexographic, gravure printing, or spin and spray coating.
