摘　　要：机械互锁聚合物是一类由机械键构成的特殊拓扑材料,其内部丰富的分子内运动赋予材料独特的性能。流变学作为揭示聚合物结构与性能关系的研究手段,在机械互锁聚合物的研究中展现出独特的魅力。本文重点综述了利用流变学方法探究机械互锁聚合物构效关系的最新进展。首先讨论了机械互锁聚合物中机械键的微观运动,然后分析了机械键运动对材料力学行为及黏弹性的影响;最后,简要总结了机械互锁聚合物流变学研究中的挑战,并展望了其未来的发展方向。Mechanically interlocked polymers(MIPs)are a unique class of topological materials composed of mechanical bonds,where the rich intramolecular motions impart the materials with distinctive properties.Rheology,as an efficient tool for elucidating the structure-properties relationships of polymeric materials,has shown particular appeal in the study of MIPs.This paper provides a focused review of the latest advances in using rheological methods to explore the structure-property relationships of MIPs.The review first examines the microscopic motions of mechanical bonds within MIPs,followed by an analysis of how these mechanical bonds influence the mechanical behaviors and viscoelasticity of mechanically interlocked materials.Finally,the challenges in the rheological study of MIPs are briefly summarized,and future directions for related research are discussed.
