Abstract: Processes for chemically treating polyaromatic feedstock to form aromatic-containing oligomers or polymers are provided. The processes are characterized by treatment of a plurality of different polyaromatic hydrocarbon molecules and/or polyheterocyclic molecules present in polyaromatic feedstock with a first reagent so as to functionalize the molecules. Further treatment in a second step affords oligomeric or polymeric products which may be crosslinked. The products may be thermoplastic or thermoset materials and may find use in, for example, infrastructure applications, composites, fillers, fire retardants and 3-D printing materials.

Abstract: The present disclosure relates to methods for using functional molecules and other structural carbon-based molecules with rigid backbones and kinked segments to alter the interactions between molecules, and consequently improve/modify the properties of materials. In particular, the disclosure provides methods for using functional molecules and other structural carbon-based molecules with rigid backbones and kinked segments as (1) precursors for carbon fiber, (2) “molecular agents” to separate and/or link π-π stacked aromatic systems, 3) stabilizers in composite materials to achieve better blending of matrix with fiber reinforcement, and/or (4) one of the components in carbon fibers to achieve better mechanical properties.
