摘要

设计了一个高分子材料与工程专业的综合性实验。利用红外光谱仪(FT-IR)、紫外可见光谱仪(UV-Vis)、差示扫描量热仪(DSC)和热重分析仪(TG)四种分析方法对生活中常见可乐瓶所用的三种材料进行了剖析。实验表明

瓶盖材料为聚乙烯(PE)

瓶身材料为聚对苯二甲酸乙二醇酯(PET)

商标材料为聚丙烯(PP)

合理地解释了不同材料分类回收的现象。该实验加深了学生对高分子材料结构与性能的认识

己多年应用于实验教学中

教学效果良好。

Abstract

A comprehensive teaching experiment for polymer material and engineering was designed in the paper. Three materials with pepsi bottle were analysed by FT-IR

UV-Vis

DSC and TG

The compositions of three materials (PE

PET

PP) with pepsi bottle were determined

and provide reasonable explanation for a common phenomenon in the daily life

that is

every material should be recycled separately. The comprehension between structure and properties of polymer materials was enhanced by this experiment. Effective teaching performance was obtained in several years.
