Polyacrylonitrile (PAN) fibers were fabricated via a dry-jet wet-spinning technique, and a solvent-free coagulation bath system was adopted. The effects of different types of dope solvent on the formation and physical properties of the PAN fibers were investigated. Dimethylformamide and dimethyl sul...
