Abstract: Polymer-nanocarbon composites, fiber-reinforced polymer composites, carbon matrix-nanocarbon composites, fiber-reinforced carbon matrix-nanocarbon composites, and methods for their manufacture are provided. The composites comprise one or more nanocarbon materials, optionally comprise fibers, and are produced from one or more polymers containing aromatic hydrocarbon moieties and/or aromatic heterocyclic moieties. The composite matrices may comprise thermoplastics or thermosets and may find use in, for example, infrastructure applications.

Abstract: Isotropic pitch compositions may be obtained by reacting an aromatic feedstock comprising one or more aromatic classes with formaldehyde or paraformaldehyde under acidic conditions. Isotropic pitch compositions may comprise: at least two monomers linked with at least one methylene bridge between each one of the at least two monomers, wherein each one of the at least monomers comprises one or more aromatic classes comprising one or more 5-membered rings, 6-membered rings, and any combination thereof; and wherein the isotropic pitch composition has a weight average molecular weight (Mw) of about 300 g/mol to about 1,500 g/mol, a softening point (Tsp) of 90° C. or greater, and a micro carbon residue (MCR) of about 18 wt % or greater, based on the total weight of the isotropic pitch composition.

Abstract: Processes and systems for producing isomeric mixtures of aromatic amine monomers from aromatic feeds. An example process for producing isomeric mixtures of aromatic amine monomers from aromatic feeds may include nitrating at least a portion of an aromatic feed to produce a mixture of nitrated aromatic compounds. The example process may further include hydrogenating at least a portion of the nitrated aromatic compounds to produce an isomeric mixture of aromatic amine monomers. The example process may further include processing the isomeric mixture of aromatic amine monomers to form a product selected from an aromatic compound with a different functional group than the aromatic amine monomers, a polymerized product, or a reaction product of the aromatic amine monomers and H2S.
