The present disclosure relates to an improved method for preparing carbon fiber via modified stabilization and carbonization methods during a process of forming filaments of co-polymers comprising acrylonitrile (AN) and vinyl imidazole (VIM) by adding an additive during the during the extrusion process to decrease stabilization temperature, increase crosslinking during oxidation, or decrease the temperatures of carbonization.

Additive for thermal production and reinforcement of carbon fiber, and carbon fiber prepared there from

A quad-polymer composition includes monomers of (a) acrylonitrile, (a) vinylimidazole, (c) methyl acrylate and (d) either acrylic acid or itaconic acid. Such quad-polymer compositions may be used to form fibers (such as by melt spinning) that may then be annealed, stabilized, and/or carbonized to produce carbon fibers. The quad-polymer composition may be used for supercapacitors, lithium battery electrodes once carbonized, and as synthesized, it may be used for wound healing fibers, fabrics, coatings, and films, and anti-bacterial/anti-microbial fibers, fabrics, coatings and films. The carbon fibers formed from the quad-polymer composition may be used for the fiber composites for automobile, aerospace structures, marine structures, military equipment/parts, sporting goods, robotics, furniture, and electronic parts.

Quad-polymer precursor for producing carbon fiber, method for producing same and method for using same

The invention is directed to melt-processable carbon fiber precursors which have the capability of thermal stabilization in air followed by carbonization in inert atmosphere which make them cost effective and widen their applications.
