Relaxation behavior of C 60 molecules between order-disorder phase transition and glassy transition is studied by extremal dynamic model. 用极限动力学模型研究了C60分子在有序-无序相变和玻璃态相变间的驰豫行为。
Molecular dynamics simulation of glassy transition of single chain polypropylene 分子动态模拟研究聚丙烯单链的玻璃化转变
The heat properties of the composite were studied by DMA and TGA. The results showed that when the content of CNTs was less than 1.0%, the glassy transition temperature of the composites lower than that of PMMA and the decomposition point had no evidently change; DMA和TGA的研究表明,碳纳米管用量少于10%的复合物玻璃化温度降低,分解温度无显著变化。
The glassy transition temperature of ion implanted layer decreases along with the increase of dose, the decrease of the glassy transition temperature is independent of implanted ion type. 注入层的玻璃化转变温度随注入剂量的增加而降低,玻璃化温度降低和注入离子的种类无关。
Dynamic Mechanical Analysis ( DMA) indicates that store modulus of epoxy/ MMT_ ( DDA) nanocomposites is not improved in glassy region, but have an increase in glass transition region. 动态热机械性能(DMA)分析表明,环氧树脂/MMTDDA纳米复合材料的储能模量在玻璃态没有明显改善,但在玻璃化转变区具有一定的提高;
The relation of the change of glassy transition temperature ( T g) of PET fiber during the later spinning process with the multipe structure of PET fiber was also studied. 并讨论了涤纶纤维在后加工过程中玻璃化温度(Tg)与纤维聚集态结构的关系。
The experiment results show that the highly flexible chain segment movement of siloxane backbone near or higher than the glassy transition temperature supplies enough free room for the movement of mesogens. 结果表明:在环硅氧烷液晶玻璃化转变温度附近(或以上)对其进行长期的热处理过程中,高度柔性硅氧烷主链链段的运动为介晶基元的运动提供了充分的自由空间;
