Abstract
Through cutting-edge scientific research, an innovative comprehensive chemical experiment has been developed for polymer or chemistry majors: A self-healing oxidized sodium alginate-carboxymethyl chitosan hydrogel (OSA-CMCS) with self-healing properties was synthesized based on dynamic imine bonds. In this study, sodium alginate was oxidized with sodium periodate as an oxidant, and a self-healing OSA-CMCS hydrogel was prepared by reaction with Schiff base of carboxymethyl chitosan. The experimental procedures include the operation of chemical experiments, analysis of instruments, spectral analysis, etc., covering the content of chemistry courses in a comprehensive manner, stimulating students’ interest in scientific research. It provides a solid foundation for undergraduate graduation projects, scientific research training projects, and the development of future scientific research.
