Abstract: Changes of surface shape, aggregate state, and microstructure of Apocynum fiber before and after irradiation were studied by XRD, IR, SEM, ESR, and solid state 13C CP/ MAS NMR. The results show that the surface shape and microstructure were not spoiled under 50 kGy gamma irradiation, while the crystallization of Apocynum fiber changed under 280 kGy . It also shows that different free radicals appear after irradiation and their concentration increases with the increase of irradiation dose.

Key words: XRD, IR, SEM, ESR, CP/ MAS, Hydrogen bond, Free radical
