以玻璃化转变温度(T_g)串联的高分子物理教学探究

Study of the Glass Transition Temperature (T_g) as the Series Connection in Polymer Physics Teaching

高分子物理作为高分子学科体系的重要组成部分,是高分子化学与物理专业、高分子材料专业及其关材料专业的一门核心基础课程,也是为后续开设相关专业课程进行铺垫的基石。高分子物理作为一门交叉学科涉及大量的数学、物理及化学知识,且知识繁杂,理论抽象,章节间缺乏系统性和整体性,给初学者造成了巨大难度和挑战。本文介绍了以玻璃化转变温度(T_g)串联高分子物理教学这一方法,即以玻璃化转变温度(T_g)这一概念及与之相对应内在的分子链运动与构象(柔顺性)和外在宏观性能之间的关系讲授串联高分子物理基础知识,帮助学生快速融会贯通和建立系统的高分子物理知识框架体系。

Polymer physics,as a major part of polymer discipline system,is a core basic course for the specialties of polymer chemistry and physics,polymer materials and related materials,and also behaves as a necessary cornerstone course for the follow-up professional courses.Polymer physics,as an interdisciplinary subject,involves a large number of mathematics,physics,and chemistry knowledge,and exhibits characteristics of much more contents and points,complex and abstract theory,lack of systematicness and integrity,which makes it very difficult for students to learn,master and use.Therefore,in this paper a teaching method of using glass transition temperature(T_g)as the series connection was introduced in polymer physics teaching.To be specific,by using the concept of glass transition temperature(T_g)and the relationship between the internal molecular chain movement with conformation(flexibility)change and external macroscopic properties as series connection to help college students quickly learn and master the basic knowledge of polymer physics,and establish a systematic polymer knowledge framework system.
