摘　　要：实验选择多种芳香族二胺和二酐单体,通过溶液聚合的方法合成二元或多元结构的聚酰胺酸溶液,后经溶液流延及热亚胺化处理制得相应结构的聚酰亚胺薄膜。通过对聚酰胺酸和聚酰亚胺结构、性能的测试与表征,探究不同单体、组成等因素对聚酰亚胺性能的影响。本实验密切衔接产业实践,实验步骤与产业研究开发过程相一致,在促进学生深入理解高分子材料结构与性能关系的同时,可激发学生的创新创业思维,培养学生分析、解决实际工程问题和项目开发的能力。Various aromatic diamines and dianhydride monomers were selected to synthesize binary or multistructured polyamide acid solutions by solution polymerization,and the corresponding structured polyimide films were prepared by solution casting and thermal amination.The effects of different monomers,compositions,and other factors on the properties of polyimide were explored by testing and characterizing the structures and properties of polyamide acid(PAA)and polyimide(PI).This experiment is based on industrial practice,which is consistent with the process of industrial research and development.Encouraging students to deeply understand the relationship between the structure and performance of polymer materials can stimulate their innovative thinking and cultivate their ability to analyze and solve practical engineering problems.
