Abstract: The present disclosure relates to methods for preparing materials from heavy feedstocks. In particular, the disclosure provides a chemical process to convert heavy feedstocks with predominant polyaromatic hydrocarbon molecules or species, including the residues of petrochemical refining or extraction, into thermoset or thermoplastic materials that can be used alone or as a component in a composite material.

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.
