Radiation chemistry of polymers has become of great interest in recent times, and may induce several changes in the structure of polymers, such as crosslinking, grafting, and chain scission. This study aims at elucidating the effects of electron beam irradiation on the stabilization reactions of polyacrylonitrile (PAN) nanofiber mats. PAN nanofiber mats were fabricated by an electrospinning process. The electrospun PAN nanofiber mats were irradiated with a 1.14 MeV electron beam energy at various doses. Radiation-stabilized PAN nanofiber mats were carbonized in a tube furnace in the presence of nitrogen at 1,000 ℃ for 1 h. The PAN nanofiber mats were characterized by SEM, FT-IR, DSC, and TGA. |
