Abstract
A manufacturing method for a carbon fiber includes the following steps. A first monomer and a second monomer are dissolved in a first solvent, and a polymerization reaction is performed to form a copolymerized polymer, in which the first monomer includes acrylonitrile, the second monomer has an unsaturated bond, the first solvent includes dimethyl sulfoxide, and based on 100 wt % of the first solvent, a content of the dimethyl sulfoxide is between 99.9 wt % and 100 wt %. A spinning step is performed on the copolymerized polymer.
