用ＷＡＸＤ和ＳＡＸＳ方法研究了聚酰胺１０１０的聚集态结构和结晶结构的辐射损伤过程和机理。辐射交联与裂解主要在非晶区和结晶表面或中间相发生；辐射损伤并从这里开始，随辐射剂量增大，非晶化逐渐向晶区伸展，有氢键的（０１０）晶面损伤几率高于（１００）晶面；辐射后效应导致新的交联与裂解生成，主要影响（０１０）晶面的形成与完善，使Ｌ１００及Ｗｃ变小。 The WAXD and SAXS methods were used to study the radiation damage process and mechanism of the aggregation structure and crystal structure of polyamide 1010. Radiation cross-linking and cleavage occur mainly in the amorphous and crystalline surfaces or in the mesophase; the radiation damage begins and begins here. As the radiation dose increases, the amorphization gradually extends into the crystalline region, with hydrogen-bonded (010) crystal plane damage The probability is higher than that of the (100) crystal plane. The post-irradiation effect leads to the formation of new cross-links and cleavages, which mainly affect the formation and perfection of the (010) crystal plane and make L100 and Wc smaller.
