    • Effect and mechanism of γ -ray irradiation on cyclic olefin copolymer in the sterilization dose range

    • “Cycloolefin copolymer COC is widely used in the field of medical devices, but irradiation sterilization can cause performance changes. Research has found that the concentration of free radicals generated by irradiation increases with increasing dose, leading to the breakage and oxidative degradation of COC molecular chains, and enhancing surface hydrophilicity.”
