| Abstract: | In recent years, people more and more pay attention to the energy ray radiation chemical method due to a powerful means of polyurethane modification. This paper, the effects of radiation on the structure and properties of polyurethane were reviewed. The main radiation chemical method of polyurethane modification were introduced, here, the progress in the radiation crosslinking and radiation grafting of polyurethane were reviewed mainly. Finally, the biomedical application of polyurethane modified by radidtion chemistry were discussed. |
