摘　　要：针对我校高分子专业学生,依托“聚合物表征与测试”课程,设计了“热分析在环氧树脂研究中的应用”综合性实验。利用“热分析技术”中的热重分析(TGA)、差示扫描量热(DSC)、动态热机械分析(DMA)和热重红外联用(TGA/FTIR)检测了实验室合成的阻燃环氧树脂(EP)材料。分析了环氧树脂的固化条件、热稳定性、玻璃化转变温度和逸出气体成分,并拓展实验内容,结合材料热性能数据探讨阻燃机理。实验结束后,通过数据共享,实现学生在有限时间内完成复杂的综合性实验。实验和教师科研相结合,注重分析思路和测试方法的相关延伸教学,提高学生在实验过程中遇到问题,分析问题和解决问题的能力。Based on the course of"polymer characterization and testing",a comprehensive experiment of"Application of thermal analysis in epoxy resin research"was designed for the students majoring in polymer in our university.The flame retardant epoxy resin(EP)synthesized in the laboratory was tested by thermogravimetric analysis(TGA),differential scanning calorimetry(DSC),dynamic thermomechanical analysis(DMA)and thermogravimetric infrared(TGA/FTIR).The curing conditions,thermal stability,glass transition temperature and escaping gas composition of epoxy resin were analyzed.The experimental content was expanded,and the flame retardant mechanism was discussed combined with the material thermal performance data.After the experiment,through data sharing,students can complete complex comprehensive experiments in limited time.Combine experiment with teachers'scientific research,pay attention to the relevant extended teaching of analysis ideas and test methods,and improve students'ability to analyze and solve problems in the process of experiment.
