Abstract:
Co-dispersions of different types of graphenic carbon particles are produced using a polymeric dispersant. A portion of the graphenic carbon particles may be thermally produced. The polymeric dispersant may include an anchor block comprising glycidyl (meth)acrylate, 3,4-epoxycyclohexylmethyl(meth)acrylate, 2-(3,4-epoxycyclohexyl)ethyl(meth)acrylate, allyl glycidyl ether and mixtures thereof, reacted with a carboxylic acid comprising 3-hydroxy-2-naphthoic acid, para-nitrobenzoic acid, hexanoic acid, 2-ethyl hexanoic acid, decanoic acid and/or undecanoic acid. The polymeric dispersant may also include at least one tail block comprising at least one (meth)acrylic acid alkyl ester.
Abstract:
A method is disclosed for making graphenic carbon particles. The method includes introducing a hydrocarbon precursor material into a thermal zone (20), heating the hydrocarbon precursor material in the thermal zone to form the graphenic carbon particles from the hydrocarbon precursor material, and collecting the graphenic carbon particles. The hydrocarbon precursor material may comprise a hydrocarbon and/or methane capable of forming a two-carbon-fragment species. Apparatus (20) for performing such a method, and graphenic particles produced by the method, are also disclosed.

Abstract:
A method of forming a coating layer on a glass substrate in a glass manufacturing process includes: providing a first coating precursor material for a selected coating layer composition to at least one multislot coater to form a first coating region of the selected coating layer; and providing a second coating precursor material for the selected coating layer composition to the multislot coater to form a second coating region of the selected coating layer over the first region. The first coating precursor material is different than the second precursor coating material.
