Abstract:

Taking polyimide (PI), a class of high-performance polymer materials, as an example, a comprehensive experimental project on polymer chemistry has been designed: "The preparation of polyimide films and their performance". The project introduces the "neck sticking" problem of the new material industry to undergraduate teaching, which includes experimental content, such as polymer design, compound synthesis, film processing, and film performance characterization. It covers topics, such as molecular simulations, spectral analysis, and the relationship between polymer structure and performance. Through experimental teaching, students can understand the development of China's new material field, develop a comprehensive knowledge of chemistry and materials, and cultivate scientific research literacy, innovation, and mission bearing spirit.

Key words: Polyimide, Molecular simulation, Polymerization reaction, Comprehensive experiment
