Various aromatic diamines and dianhydride monomers were selected to synthesize binary or multi-structured 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.
