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: 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.
