Abstract: A method of producing a surface modified low hysteresis carbon black or a refined surface modified low hysteresis carbon black compound includes treating a surface of a low hysteresis carbon black with about 0.1% weight by volume to about 50% weight by volume of surface modifying agent in a solvent, and heat treating the surface of the low hysteresis carbon black following the treatment of the surface with the surface modifying agent to form a surface modified low hysteresis carbon black compound, wherein the surface modifier includes at least one amine group and at least one thiol group and/or di- and/or polysulfidic linkage.

Abstract: Non-ASTM low hysteresis carbon blacks chemically treated, and surface coated with a compound comprising at least one amine group and at least one thiol group, and/or di- and/or polysulfidic linkage. When compared with a standard ASTM grade compound, the disclosed surface modified low hysteresis carbon black compound shows improved rolling resistance, wet traction, and DIN abrasion, comparable to silica compounds.

Abstract: A surface modified and functionalized carbon black for use in a rubber compound suitable for tire tread compounds which can be described as a surface modified low hysteresis carbon black. The modified carbon black contains a chemical consisting of at least one amine group and at least one thiol group and/or di- and/or polysulfidic linkage. The surface modified low hysteresis carbon black in a representative rubber tire tread compound shows improved rolling resistance, improved wet traction, and improved or maintained abrasion resistance, being superior to compounds containing N234 carbon black or silica. The improved tire rolling resistance obtained by using a compound containing a surface modified low hysteresis carbon black is highly desirable for reduced CO2 emissions, reduced pollution, sustainability, and protection of the environment.

Abstract: A method for separating single-wall carbon nanotubes from an aqueous slurry comprises adding a water-immiscible organic solvent to an aqueous slurry comprising single-wall carbon nanotubes, isolating at least some of the single-wall carbon nanotubes in the solvent, and removing the solvent from the single-wall carbon nanotubes to form dried single-wall carbon nanotubes. A spheroidal aggregate of single-wall carbon nanotubes is formed wherein the aggregate is approximately spherical and has a diameter in a range of about 0.1 and about 5 mm, and wherein the aggregate contains at least about 80 wt % single-wall carbon nanotubes. The spheroidal aggregates of single-wall carbon nanotubes are easily handled in industrial processes and are redispersable to single-wall carbon nanotubes and/or ropes of single-wall carbon nanotubes. This invention can also be applied to multi-wall carbon nanotubes.
