【摘要】：离子作用的可逆性赋予了含离子聚合物丰富的力学和电学性能,使其广泛应用在高抗冲材料、记忆材料、自修复材料和智能响应材料等新兴领域.本专论结合作者近年的研究工作,介绍了含离子聚合物体系的构效关系和分子流变学,从3个方面展开:第1部分介绍了对于含离子聚合物的离子聚集状态的调控,和离聚物与聚电解质的相互转化;第2部分介绍了离子高度聚集的无规离聚物丰富的线性黏弹性,重点介绍了非缠结体系在链均一个离子浓度附近区域的溶胶凝胶转变以及缠结体系在平均每个缠结链段一个离子浓度附近区域的单平台到双平台模量的转变;第3部分介绍了如何进行分子设计,使得含离子聚合物成为有效的离子传输介质.最后总结了该研究领域的科学问题和面临的挑战.
[Abstract]:The reversibility of ionic interaction gives ionic polymers rich mechanical and electrical properties, making them widely used in high impact materials, memory materials, This monograph introduces the structure-activity relationship and molecular rheology of ion-containing polymer systems in combination with the authors' recent research work, such as self-repairing materials and intelligent response materials. The first part introduces the regulation of ionic aggregation state of ionic polymers and the interaction between ionomers and polyelectrolytes, and the second part introduces the rich linear viscoelasticity of random ionomers with high ion concentration. The sol-gel transition of the non-entangled system in the region near the concentration of one ion per chain and the transition of the single-platform to the bi-platform modulus of the entangled system in the region near the average concentration of one ion per entangled chain are introduced. In the third part, we introduce how to design the molecule to make the ion-containing polymer become an effective ion transport medium. Finally, the scientific problems and challenges in this field are summarized.
