Polymer-topology effects can alter technologically relevant properties when cyclic macromolecules are applied within diverse materials formulations. These include coatings, polymer networks, or nanostructures for delivering therapeutics. While substituting linear building blocks with cyclic analogues in commonly studied materials is itself of fundamental interest, an even more fascinating observation has been that the introduction of physical or chemical boundaries (e.g., a grafting surface or cross-links) can amplify the topology-related effects observed when employing cyclic polymer-based precursors for assembling multidimensional objects. Hence, the application of cyclic polymers has enabled the fabrication of coatings with enhanced biorepellency and superior lubricity, broadened the tuning potential for mechanical properties of polymer networks, increased the thermodynamic stability, and altered the capability of loading and releasing drugs within polymeric micelles.

拓扑高分子化学进入材料科学：拓展环状高分子的适用性

当环状大分子应用于不同的材料配方时，聚合物拓扑效应可以改变技术相关的特性。这些包括用于提供治疗的涂层、聚合物网络或纳米结构。虽然在通常研究的材料中用环状类似物代替线性结构单元本身就很有趣，但更有趣的观察是引入物理或化学边界（例如，接枝表面或交联）可以放大与拓扑相关的使用基于环状聚合物的前体组装多维物体时观察到的效果。因此，环状聚合物的应用使得能够制造具有增强的生物排斥性和优异润滑性的涂层，
