聚合物玻璃化转变的本质一直是困扰材料科学工作者的一个难题,也吸引了众多学者利用各种测试手段对其进行研究。由于对聚合物的结构较为敏感,傅里叶变换红外光谱(FTIR)被广泛应用于研究聚合物在玻璃化转变期间的构象变化。对此有相当数量的研究报道,本文对这些研究工作进行了介绍。目前用FTIR对玻璃化转变的研究工作大多集中于转变过程中构象的变化,在今后的工作中,如何充分利用FTIR方法的优势,对聚合物玻璃化转变展开更为丰富的研究,应当成为研究工作者们努力的方向之一。
The nature of polymer glass transition has always been a problem for material scientists, and it has also attracted many scholars to use various testing methods to study it. FTIR has been widely used to study the conformational changes of polymers during their glass transition due to their sensitivity to the structure of polymers. There is a considerable amount of research on this, this paper describes these research work. At present, the research on the glass transition by FTIR mostly focuses on the conformational changes in the process of transformation. How to make full use of the advantages of FTIR method in the future work to develop a more abundant research on the glass transition of polymers should be studied One of the directions that workers are trying hard.
