摘要

玻璃化转变是聚合物的一种普遍现象

也是高分子物理教学过程中的一个重点内容。对玻璃化转变的本质进行深入透彻地讲解

有利于学生加深对高分子结构、高分子材料的性能和高分子链运动的统计学三个紧密相连部分的融会理解。针对目前教学过程中主要基于差示扫描量热法进行非晶态聚合物玻璃化转变温度概念讲解的不足

本论文交流了在教学过程中采用红外光谱(FTIR)及二维相关光谱讲解玻璃化转变温度时的运用以及教学效果分析。从实际的教学效果看

应用FTIR 确定聚合物的玻璃化转变温度既可以培养学生的探索精神

又能使学生了解新的研究方法并拓宽科学视野。

Abstract

Glass transition

as a common phenomenon of polymer

is a key content in polymer physics teaching. A comprehensive explanation of the nature of glass transition is helpful for students to deepen their understanding of polymer structure

properties of polymer materials and statistics of polymer chain motion. Aiming at the deficiency of the concept of glass transition temperature of amorphous polymer mainly based on differential scanning calorimetry (DSC)

this paper discussed the application of Fourier transform infrared spectroscopy (FTIR) and two-dimensional correlation spectroscopy to explain the glass transition temperature and the analysis of teaching effectiveness. From the actual teaching effectiveness

the application of FTIR to determine the glass transition temperature of polymer can not only cultivate students' exploration spirit

but also make students understand new research methods and broaden their scientific vision.
