摘　　要：自修复聚脲因其优异的自修复效应和良好的韧性,在柔性电子器件、仿生电子皮肤、软机器人等前沿科技领域展现了广阔的应用前景。采用异佛尔酮二异氰酸酯和聚醚胺D-400为原料,在无水无氧的条件下合成聚脲,通过红外光谱进行结构鉴定,并对产物的自修复性能和韧性进行研究,同时探明产物性能与结构之间的密切关系。结果表明:所得聚脲具有优异的自修复效果,6 h后自修复效率可达91%,具有良好的韧性。实验以“高分子化学合成-结构鉴定-性能测试”为逻辑主线,具有较强的学科综合性,能够拓宽学生的学术视野,激发学习兴趣,在夯实基础理论知识和实验操作技能的基础上,培养研究性学习实践的能力和素养。Due to its excellent self-healing effect and good toughness,self-healing polyurea has shown broad application prospects in flexible electronic devices,bionic electronic skin,soft robots and other cutting-edge technology fields.In this experiment,isophoronediisocyanate and polyether amine D-400 were used as raw material to synthesize polyurea under water-free and oxygen-free conditions.The structure of the product was identified by infrared spectrum,and the self-healing properties and toughness of the product were studied to clarify the close relationship between the structure and properties of the product.The obtained polyurea has excellent self-healing effects,and the self-healing efficiency can reach to 91%after 6 h,also with good toughness.This experiment takes"polymer chemical synthesis-structure identification-performance test"as the main logic line,which has strong comprehensiveness;at the same time,it also enables students to broaden their academic horizon and stimulate their learning interest.On the basis of consolidating basic theoretical knowledge and experimental operation skills,the investigative learning ability is cultivated.
