摘要

橡胶分子链独有的柔顺性和熵弹性特征

使其表现出巨大形变能力和明显的弹热效应。近年来基于橡胶回缩-吸热机理的弹热制冷现象逐渐受到重视

从而为高分子物理学的研究开辟了一个新的方向。本文在“高分子物理学”课程高弹形变和弹热效应的热力学分析基础上

引入橡胶弹热制冷效应的原理与研究进展

设计“基于橡胶熵弹性的弹热制冷效应”的教学目标、教学过程等内容

不仅有助于将抽象的高分子物理学基础理论转化为实际应用范例

提升“高分子物理学”课程的学习质量

还锻炼了大学生跟踪学科前沿、开展创新训练的意识与能力。

Abstract

Due to the unique flexibility and entropy elasticity of molecular chain

rubber shows great deformability and obvious caloric effect. In recent years

the research of elastocaloric refrigeration based on rubber stretch-removal endothermic mechanism has attracted more and more attention

which opens up a new direction for the research of polymer physics. Based on the thermodynamic analysis of high elastic deformation and elastocaloric effect in the course of "Polymer Physics"

this paper introduces the principle and research progress of rubber elastocaloric refrigeration effect

and designs the teaching objectives and teaching process of "refrigeration effect of rubber entropy elasticity". It not only helps to transform the abstract basic theory of polymer physics into practical application examples

improving the learning quality of polymer physics

but also exercises the consciousness and ability of college students to track the frontier of disciplines and carry out innovative training.
