Zhong-yu FU, Bai-jun LIU, Hui-xuan ZHANG, Chao ZHOU, Guang-feng WU. Application of Infrared Spectroscopy and Two-dimensional Correlation Spectroscopy in Explaining the Concept of "Glass Transition" of Polymers[J]. Polymer Bulletin, 2022,35(5):102-106.
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.
