  • Publication number: 20140290532
    Abstract: A process for producing surface modified carbon black is disclosed. The process comprises the step of treating carbon black with a sulfur compound in an amount in the range of 0.005%-1% of the carbon black to effect in situ formation of surface groups to produce the surface modified carbon black which when combined with a polymer composition alters the carbon black-polymer interaction to decrease the hysteresis of the polymer composition. The curing time required for polymer composition comprising the surface modified carbon black is also decreased. The preferred sulfur compounds are sulfite or sulfate salts.

  • Patent number: 7939595
    Abstract: A method for reducing cure shrinkage of a thermoset resin includes forming a plurality of surface modified nanofibers. The surface modified nanofibers are formed by soaking nanofibers in an oxidizing acidic solvent. An oxidizing agent is added to the soaking nanofibers, thereby generating heat sufficient for at least one of in-situ oxidation and in-situ exfoliation of a subsurface of each of the nanofibers. Excess oxidizing agent and acidic solvent are removed from the nanofibers, which are then dried. The dried nanofibers have reduced surface hydrophobicity. The surface modified nanofibers are substantially uniformly dispersed into the thermoset resin. The surface modified nanofibers are adapted to reduce cure shrinkage of the thermoset resin during subsequent curing processes.

  • Patent number: 6494946
    Abstract: Processes for preparing a carbon black product having an organic group attached to the carbon black. In one process at least one diazonium salt reacts with a carbon black in the absence of an externally applied electric current sufficient to reduce the diazonium salt. In another process at least one diazonium salt reacts with a carbon black in a protic reaction medium. Carbon black products which may be prepared according to process of the invention are described as well as uses of such carbon black products in plastic compositions, rubber compositions, paper compositions, and textile compositions.

  • Patent number: 6402825
    Abstract: The invention provides a surface modified carbon black and method for production. The surface modified carbon black is produced by reacting self-dispersing or oxidized carbon with a steric inducing compound via an organic acid halide intermediary. The steric inducing compounds are substantially soluble in the organic components of an ink composition and are reactive with an organic acid halide. Electrostatic and steric stability are provided by the surface modified carbon black. The surface modified carbon black exhibits solubility in aqueous and organic media and exhibits excellent resistance to coagulation within an ink jet printhead.

  • Patent number: 6221142
    Abstract: The ink of the invention comprises a vehicle and a colorant. The colorant is a water-insoluble pigment that has been chemically modified to be water dispersable by addition of functional groups to the surface of the pigment resulting in water soluble colorant particles. The performance of these pigments is improved by the addition of specific functional groups which provide improved black to color bleed control and high waterfastness.
