  • Patent number: 10087330
    Abstract: The invention is directed to processes for increasing the surface area of a carbon black starting material and for forming mesoporous carbon black. The process includes the step of contacting a carbon black starting material having a first BET nitrogen surface area with an oxidant in a fluidized bed under conditions effective to form a carbon black product having a second BET nitrogen surface area greater than the first BET nitrogen surface area. The invention is also directed to carbon black product formed by this process.

  • Patent number: 9053871
    Abstract: The present invention, in part, relates to a carbon black having a) a nitrogen BET surface area (BET) of from about 600 m2/g to about 2100 m2/g, b) a CDBP value in mL/100 g of from about (?2.8+(b*BET)) to about (108+(b*BET)), where b is 0.087 and BET is expressed in m2/g, and c) an apparent density (p, g/cm3) of at least about 0.820+q*BET, where q=?2.5×10?4, as determined at a compressive force (P) of 200 kgf/cm2 on dry carbon black powder. Energy storage devices, such as electrochemical double layer capacitors (EDLC's), containing the carbon black are also disclosed. Methods for making the carbon blacks and EDLC's made with them are also provided.

  • Patent number: 5468532
    Abstract: A multilayer graphic article comprises a substrate, at least one color layer disposed on the substrate, and a protective surface layer that overlies the substrate and the color layer. The color layer is visible through the surface layer and comprises a color agent in a copolymeric binder. The binder comprises the copolymerization product of an olefinic monomer and a second monomer having a pendant carboxyl group. The substrate may be a polymeric film, an adhesive or a temporary, removable liner. The protective surface layer may be formulated to impart interior surface protection properties to the graphic article or it may be formulated to render the graphic article weatherable and resistant to chemical exposure.

  • Patent number: 5405675
    Abstract: An embossed multilayer film comprises an embossed base layer and a conformable, substantially uniformly thick protective surface layer that overlies the base layer. In one embodiment, the embossed multilayer film can be re-embossed. In another embodiment, the surface layer is provided by a polyurethane-based material. The invention also relates to a method of providing such an embossed multilayer film.
