摘　　要：超分子聚合物由于其结构中存在的动态和可逆的非共价相互作用,表现出包括自修复性、刺激响应性和力学适应性等许多独特的动态特性,因而在智能材料的设计和制造中显示出巨大的潜力。作为一种典型的非共价作用,金属配位作用被广泛应用于构筑聚合物材料,并发展出金属超分子聚合物这一重要概念。相较于其他超分子作用,金属配位作用具有可预测的组装结构以及更高的键合强度等独特优势,这些特性对于聚合物拓扑的精准构筑和力学性能的有效改善有着重要的意义。因此,本研究从金属超分子聚合物出发,详细论述了该类聚合物在构筑聚合物拓扑和调节力学性能方面的重要进展,并基于现有的研究进展对金属超分子聚合物的发展进行展望。Due to the dynamic and reversible noncovalent interactions,supramolecular polymers exhibit various unique dynamic properties,including self-healing ability,stimuli-responsiveness and mechanical adaptability,and thus show great potentials in the design and preparation of smart materials.As one of typical noncovalent interactions,metal coordination has been widely used in the construction of polymer materials,and a significant concept of metallo-supramolecular polymers(MSPs)has been developed.Compared with other supramolecular interactions,metal coordination has the unique advantages of predictable assembly structures and higher bonding strength,which are important for the accurate construction of topological polymers and effective improvement of mechanical properties.As a result,this review has a detail discussion about the significant progress of MSPs in the construction of polymer topology and the regulation of mechanical properties.Moreover,an outlook is then given to highlight the future opportunities and challenges in the development of MSPs based on the existing research foundation.
