Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for forming fibers of quad-polymers comprising (a) a first monomer that is acrylonitrile, (b) a second monomer that is selected from a group consisting of 1-vinylimidazole, 4-vinylimidazole, 2-vinylimidazole, and 1-methyl-2-vinylimidazole, (c) a third monomer that is selected from a group consisting of methyl acrylate, ethyl acrylate, butyl acrylate, methyl methacrylate, and tert-butyl acrylate, and (d) a fourth monomer that is an acid and is selected from a group consisting of acrylic acid, itaconic acid, and methacrylic acid, wherein the method includes the steps of: (i) combining the first monomer, the second monomer, the third monomer, and the fourth monomer to form the quad-polymer composition; and (ii) melt-spinning the quad-polymer composition to form fibers of the quad-polymer composition.
