Abstract

Taking the research hotspot of malleable thermosetting polymers

and combining it with the author’s research achievements and experimental teaching experience

a comprehensive polymer experiment project with teaching feasibility is designed by extracting contents from scientific research projects that can showcase the frontiers of the discipline and reflect academic value. The project focuses on the synthesis and properties research of recyclable thermosetting polyurethane foam. This experiment project is rich in content and comprehensive

covering relevant knowledge in polymer chemistry

polymer physics

and polymer processing. By implementing a reasonable plan and employing distinctive teaching methods

it highlights the students’ subject position in the experiment

stimulates their active learning and enthusiasm

and cultivates their research thinking and innovation ability.
