Effects of Gamma-rays Irradiation on Partially Fluorinated Polystyrene

In this study, the effects of gamma-ray irradiation on partially fluorinated polystyrene were demonstrated. Polystyrene is an organic polymer material with radiation resistance due to its aromatic structure. To improve the radiation resistance of polystyrene, poly(4-fluoropolystyrene) and polypentafluorostyrene were prepared by solution polymerization. The Co-60 gamma-ray irradiation was performed with a dose rate of 10 kGy/h in an air atmosphere. The absorbed doses were 25, 50, 100, 200, and 500 kGy, respectively. The changes in atomic composition, chemical structure, and thermal property were characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, thermal gravimetric analyzer, and differential scanning calorimetry. Based on analytical results, polypentafluorostyrene showed less oxidation and excellent thermal properties after the absorbed dose of 500 kGy. These results indicate that partially fluorinated polystyrene is a promising candidate for radiation resistance applications.
