| Abstract: | The research progress in coagulation process of PAN protofiber in wet-spinning is reviewed. The theory research of diffusion process is introduced. The effect of spinning conditions, including the bath temperature, bath concentration and the solid content in dope, on structure and properties of protofiber is described. The progress and application of PAN fiber and PAN-based carbon fiber are presented. |
