本文利用WAXD、DSC、ESR方法研究了PA1010-Nd2O3体系的辐射效应,主要讨论了结晶-非晶的界面(结晶表面)对辐射效应的影响。结论如下:结晶表面影响PA1010的辐射交联,结晶的破坏剂量因结晶表面积增大而提高。具有相同浓度的成核剂,但结晶度不同的试样,它们的结晶表面积取决于结晶度,它们的辐射效应由于微晶尺寸与结晶表面积的差异而不同。结晶度越大,微晶尺寸越大,结晶越完善,结晶的表面积越大,结晶结构不易受到γ辐照的破坏。结晶表面对结晶结构起着保护作用,进一步证明了结晶表面是结晶破坏的始点
In this paper, the radiation effects of PA1010-Nd2O3 system have been studied by WAXD, DSC and ESR methods. The influence of the crystalline-amorphous interface (crystalline surface) on the radiation effects has been discussed. The conclusions are as follows: The crystalline surface affects the radiation cross-linking of PA1010, and the destructive dose of crystallization increases due to the increase of the crystallized surface area. Samples having the same concentration of nucleating agent but different degrees of crystallinity have crystalline surface areas that are dependent on the degree of crystallinity and their radiation effects vary due to differences in crystallite size and crystalline surface area. The greater the degree of crystallinity, the larger the crystallite size, the more perfect the crystal. The larger the surface area of the crystal, the less susceptible to gamma irradiation. The crystal surface plays a protective role on the crystal structure, further confirming that the crystal surface is the starting point of crystal destruction
