Abstract The experimental teaching project of polymer science in colleges and universities is not synchronized with the development of polymer science and technology.To address this issue,this project proposes constructing interpenetrating polymer networks(IPN)and preparing conductive interpenetrating hydrogel materials with thermal-responsiveness.The thermal-response performance of these materials is measured to expand students’ understanding of the application of polymer materials in the field of electrical sensing.The experiment focuses on the research hotspot of polymer science.Students conduct a literature review and teachers grasp the depth of the introduction of scientific research achievements,followed by guiding students to design the experiment,which could be regards as a small-scale scientific research project that integrates aggregation-structure characterization-performance testing.In the experimental session,temperature or material variables are introduced into some experiments in order to simulate the process of scientific research exploration.Through data sharing and comprehensive analysis among different groups,the gradient control experiments are efficiently completed.This enables students to develop their ability well to analyze data horizontally and draw conclusions.This experiment has been implemented in undergraduate experimental teaching for two years,during which time students have been guided to win two awards in provincial and above-level disciplinary competitions,and published one paper in a Chinese core journal.The teaching implementation process has achieved a good experimental teaching effect.
