초록
Polyacrylonitrile (PAN) is one of the most widely used precursor polymers for makinghigh performance carbon fibers. Conversion of PAN fibers to good quality carbon fibers requires anessential stabilization step prior to carbonization. Electron beam irradiation is an excellent techniquefor modifying the physical properties of materials. This study aimed to elucidate the effectsof electron beam irradiation on the stabilization reactions of PAN nanofibers. FT-IR analysis indicatedthat the stabilization of irradiated PAN nanofibers was initiated at a lower temperature. TheTG curve of PAN nanofibers showed a significant decrease of weight loss step between 280 and320C. In the case of irradiated PAN nanofibers, weight loss sudden weight did not loss occurs.
