摘要:
结合科研项目以及办学特色,设计了一个创新性实验"高性能导电水凝胶制备及应用"。实验内容包括导电水凝胶的构筑,水凝胶性能测试,结构-性能相关性分析以及应用。由于疏水缔合与离子键的协同交联作用,该水凝胶的断裂伸长率和韧性为30mm/mm和10.34MJ/m3,分别是传统聚丙烯酰胺水凝胶的19和225倍。此外,该导电水凝胶灵敏度高达3.4,且能够迅速准确地感知手指弯曲等信号。该实验有效吸引了学生的注意力并提升了学生的参与热情。项目不仅能够巩固学生有机化学、分析化学、高分子化学以及材料工程的基础知识,还培养了学生的动手能力、数据分析能力和书面表达能力。
Abstract:
Based on research projects and school characteristics, a teaching experiment was designed for the fabrication and application of high-performance conductive hydrogels. The experiment includes preparation, mechanical properties, structure-property relationship, and application of the conductive hydrogel. Owing to the synergy of hydrophobic associations and ionic interactions, the obtained hydrogel displayed outstanding mechanical properties, that is, the tensile strain and toughness were 30mm/mm and 10.34MJ/m3, which were 19 and 225 times of the traditional polyacrylamide hydrogel, respectively. In addition, it exhibited gauge factor of 3.4, and could reliably monitor finger bending. This experiment captured the students’ attention and promoted their involvements. The experiment not only consolidated basic concepts in the field of organic chemistry, analytical chemistry, polymer chemistry and material engineering, but also improved their skills in conducting experiments, analyzing data and conveying information accurately.
