摘　　要：基于非共价键构建超分子弹性体是近年来超分子领域研究的热点之一,其中离子氢键因其结构简单且性能可控而受到重视。通过将该领域最新科研成果引入实验教学,设计、制备了两类结构相似但性能迥异的超分子弹性体,通过FT-IR、^(1)H-NMR、GPC、流变行为、力学性能及自愈合效率等表征手段,建立了超分子弹性体的结构与性能关系。该实验内容涵盖了聚合物合成与改性、制备方案设计和实施、聚合物结构表征等诸多环节,具有一定的综合性与探索性,有利于提高学生的综合素质,以及科研与创新能力。Supramolecular elastomers based on non-covalent bonds is one of the hotspots recently in the field of supramolecular,in which the ionic hydrogen bond associations have attract much attention for their simple structure and controllable properties.By introducing the latest scientific research achievements in this field into experimental teaching,two serials supramolecular elastomers with similar structures but different properties are designed and prepared,and relationship between structure and properties is established based on FT-IR,^(1)H-NMR,GPC,rheological behavior,mechanical properties and self-healing efficiency.The experimental content covers many subjects such as polymer synthesis and modification,preparation scheme design and implementation,polymer structure characterization and so on,it is comprehensive and exploratory to a certain extent,and is conducive to improve students'comprehensive quality,scientific research and innovation ability.
