The present disclosure relates to a process for producing carbon fibers utilizing a salt of an organic cation containing C═N imine group, and carbon fibers produced by such process.

Process for producing carbon fibers and carbon fibers made therefrom

The present disclosure relates generally to carbon fibers having high tensile strength and modulus of elasticity, as well as a process for the manufacture of such carbon fiber. The process comprises spinning a polymer/solvent solution into a solvent/water bath in the range of 78%-85% solvent, thereby producing a dense fiber structure, and subsequently carbonizing the polymer precursor fiber at a lower than typical carbonization temperature to form carbon fibers.

Manufacture of intermediate modulus carbon fiber

A method for synthesizing polyacrylonitrile (PAN) polymer with a narrow molecular weight distribution is disclosed. The preferred PAN polymer has a PDI (Mw/Mn) of about 2 or less. Such PAN polymer is synthesized by controlled/living radical polymerization using a special RAFT (Reversible Addition-Fragmentation Chain Transfer) agent. Also disclosed is a method for producing carbon fibers from PAN polymer with low PDI.
