摘要

高分子物理是高等院校高分子材料与工程专业的一门重要的专业基础课。“结晶”是高分子聚集态结构中重要的概念。巨大的分子量及长链状分子结构使高分子的结晶过程与小分子相比愈加复杂。在高分子物理课程的教学过程中，通过一定的逻辑架构向学生介绍结晶与有序、链柔性、玻璃化温度之间的关系并串联与结晶相关的一些概念(如结晶度、结晶温度、熔点以及结晶速率)，使学生在初学阶段对高分子品态结构建立起科学的认知体系。实践证明，通过这种教学方式，绝大多数同学都能较好地理解并掌握这部分教学内容。

Abstract

Polymer physics is an important professional basic course of students majoring in polymer materials and engineering. "Crystallization" is an important concept in aggregation structure of polymer. Large molecular weight and long chain molecular structure make the crystallization process of polymers more complicated compared with that of small molecules. In the teaching process of polymer physics

we introduce students the relationship between crystallization and ordered

chain flexibility

glass transition temperature

and put some concepts in series

which are related to crystallization (such as crystallinity

crystallization temperature

melting point and crystallization rate). The aim is to establish scientific cognitive system about polymer crystalline structure for students in their preliminary stage. Practices show that the majority of students have a good understanding and mastery of these teaching contents through this way.
