| Abstract: | A novel ion exchange fiber with sulfonic groups, named RPFS-I,was synthesized by introducing taurine （NHECHECH2SO3H） onto polyacrylonitrile （PAN） fiber. Taurine concentration,reaction temperature and reaction time were studied for their effects on the reaction. RPFS-I was characterized by ion exchange capacity, FTIR and stretching resistance. Results showed that sulfonic groups were successfully introduced onto PAN fiber. The ion exchange capacity of RPFS-I reached 2.7 mmol/g. The mechanical performance of RPFS-I were not evidently decreased after reaction. |
