| 英文摘要 | A theoretical rod model for investigating the polyacrylonitrile (pan) copolymer coagulation process was presented in this work. the mass transfer rate and coagulation rate under different coagulation conditions were obtained using this method. an optical microscope with image transfer software was employed to observe the coagulation boundary of the filament. the results showed that the coagulation rate decreased continuously with the increase of bath concentration. however, with the increase of the bath concentration, the mass transfer rate decreased at the beginning of the coagulation, and as the t1/2 increased, the weight loss was greater when the bath concentration was higher. moreover, the coagulation rate and mass transfer rate increased with the increase of the coagulation temperature, and the coagulation was most moderate when the bath temperature was 50 degrees c. |
