摘　　要：设计了一个高分子材料与工程专业的综合性教学实验。利用FT-IR、UV-Vis和DSC三种方法,对生活中常见的纯净水瓶(PET)和果汁瓶(PP)材料进行了剖析,确认出两种材料的组成,合理解释了当沸腾后的热水倒入纯净水瓶时,瓶体会明显变软、变形,而果汁瓶不发生变形的原因。该实验加深了学生对常用高分子材料结构与性能的认识,已应用在三届学生的专业实验教学中,教学效果良好。A comprehensive teaching experiment for undergraduate of polymer material and engineering was designed in this paper.By FT-IR、UV-Vis and DSC analysis,the compositions of bottle materials with purified water and fruit juice were determined,and provide reasonable explanation for a common phenomenon in the life,that is,purified water bottle is easy to deform when poured into boiled water,however,fruit juice bottle would be not.Effective teaching performance was obtained.
