摘要： 采用X射线粉末衍射(XRD)和差示扫描量热分析(DSC)方法, 跟踪研究了N-(1-萘基)琥珀酰亚胺的液氮淬冷样品在室温(25 益)即在玻璃化转变温度以下的冷结晶行为. DSC和XRD的结果一致表明, 其冷结晶动力学曲线与熔融结晶完全不同, 呈现出“快-慢-快的三阶段增长趋势, 这一结果可以用低密度界面区成核和体积收缩效应给予解释.

Abstract: Cold crystallization process of N-(1-naphthyl) succinimide below glass transition temperature was monitored by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The results showed that the kinetic curve of cold crystallization was completely different from that of melt crystallization, exhibiting "fast-slow-fast" three increasing stages. This result could be explained in terms of low-density-interface nucleation and volume-contraction effect.
