| Abstract: | The research progress of PAN precursor fiber in wet-spinning was reviewed from two aspects-polymerization and coagulation. The polymerization method, co-polymerization, polymer blends and modification were introduced briefly. The foundation and development of double-diffusion model in coagulation were presented. The effects of coagulation conditions such as coagulation bath composition, bath temperature and stretch radio on structure and properties of nascent fiber were discussed in detail. |
