摘要: 本文通过WAXD和DSC等方法研究了γ-辐照尼龙1010聚集态结构的变化,结晶损伤和无定形化的过程。这些过程和结晶与非晶界面原子参与化学反应密切相关,结晶损伤从结晶表面开始,随着辐照剂量增加逐渐向结晶内伸展,直到完全无定形化。

Abstract: The effect of gamma-irradiation on the state of aggregation of nylon 1010 was studied by using WAXD and DSC techniques. The results showed that the crystal damage and amorphotization induced by gamma-irradiation are closely related to the chemical reaction of atoms on the interface between crystalline and non-crystalline region of the polymer. The damaging started from the surface of the crystal and proceeded gradually into the crystal, which became completely amorphous when radiation dose was extremely high.
