综合创新设计实验:自修复水凝胶的制备及性能测试

Comprehensive Innovative Design Experiment:Preparation and Performance of Self-Healing Hydrogels

可修复水凝胶的制备是当今科学研究的热门领域,它将有机化学、高分子化学、材料化学和仿生化学结合于一体,显示出进一步改编为本科教学实验的潜力。本实验是基于琼脂糖/聚乙烯醇双网络的自修复水凝胶的制备及其自修复性能测试的新创综合实验。实验生动有趣,在实验过程中学生可对水凝胶进行多种造型和设计,能激发学生学习化学的兴趣和热情,非常适用于本科教学实验。水凝胶作为低成本、环境友好型材料,贴合绿色化学主题,也利于在实验教学中渗透可持续发展、环保等生态文明理念。

The preparation of repairable hydrogels is an extensively researched multidisciplinary topic,incorporating organic chemistry,polymer chemistry,material chemistry,and biomimetic materials.Thus,it has tremendous potential for further adaptation in undergraduate teaching experiments.Herein,we propose a novel comprehensive experiment to study the preparation and self-healing performance of self-healing hydrogels based on an agarose/PVA dual network.The experiment is vivid and interesting.Students can shape and design the hydrogels in a variety of ways during the experiment,which can stimulate students’interest and enthusiasm in learning chemistry.As a low-cost and environment-friendly material,hydrogels are also suitable for teaching the concepts of green chemistry,sustainable development,and environmental protection.
