9. "DSC and TMDSC Study of Melting Behaviour of Poly(butylene succinate) and Poly(ethylene succinate)". Qiu ZB,* Komura M, Ikehara T, and Nishi T.* Polymer 2004; 44: 7781-7785.
The subsequent melting behaviour of poly(butylene succinate) (PBSU) and poly(ethylene succinate) (PES) was investigated using DSC and TMDSC after they finished nonisothermal crystallization from the melt. PBSU exhibited two melting endotherms in the DSC traces upon heating to the melt, which was ascribed to the melting and recrystallization mechanism. However, one melting endotherm with on...

29. DSC and TEM investigations on multiple melting phenomena in isotactic polystyrene. Liu T, Yan S, Bonnet M, Lieberwirth I, Rogausch KD, Petermann J. J. MATER. SCI. 35 (20): 5047-5055, 2000.
The multiple melting behavior and morphologies of isotactic polystyrene (iPS) isothermally crystallized from the glassy state have been investigated by differential scanning calorimetry (DSC) and transmission electron microscopy (TEM). The combination of thermal analysis and morphological results indicates that two lamellar populations are responsible for the so-called double melting behavior in i...

Nonisothermal crystallization kinetics of in situ nylon 6/graphene composites by differential scanning calorimetry.
关键字：nylon 6/graphene composites, non-isothermal crystallization kinetics; differential scanning calorimetry (DSC)
The non-isothermal crystallization kinetics were investigated by differential scanning calorimetry for the nylon 6/graphene composites prepared by in situ polymerization. The Avrami theory modified by Jeziorny、Ozawa equation and Moequation were used to describe the non-isothermal crystallization kinetics. The Analysis based on the Avrami theory modified by Jeziorny shows that，at lower cooling ra...

纳米Pb和Bi的热稳定性
关键字：纳米Pb 纳米Bi 熔点 熔化焓 DSC-TG
利用综合热分析仪（DSC-TG）对纳米Pb（粒晶为90～150nm）和Bi（粒晶为90～130 nm）与体相Pb和Bi的熔点和熔化焓以及热稳定性等热力学性质进行了研究。实验结果表明：纳米Pb和Bi比块体的Pb和Bi有更高的吸附能力和化学活性。纳米Pb比块体的Pb熔点降低2.3℃，熔化焓降低59.0%，纳米Bi比块体的Bi熔点降低5.3℃，熔化焓降低47.95%。

高性能环氧树脂/沥青复合物的研究
关键字：环氧沥青 聚合物改性沥青 DSC
环氧树脂是一种聚合物改性沥青。在一定温度下环氧树脂与沥青中的固化剂和沥青质上的羧基发生反应，最终将沥青固定在环氧树脂固化后形成的交联网络中，从而从根本上改变沥青的热塑性行为，提高沥青的耐温性和力学等性能。目前，环氧沥青材料已经被广泛地用于大跨径钢桥面的铺装[1]。2000 年我国在南京长江二桥上成功铺装了进口环氧沥青，至今我国共有20多座大跨径桥梁采用进口环氧沥青进行铺装。
