Semi-crystalline polymers (SCPs) with anisotropic amorphous and crystalline domains as the basic skeleton are ubiquitous from natural products to synthetic polymers. The combination of chemically incompatible hard and soft phases contributes to unique thermal and mechanical properties. The further introduction of supramolecular interactions as noncovalently interacting crystal phases and soft dynamic crosslinking sites can synergize with covalent polymer chains, thereby enabling effective energy dissipation and dynamic rearrangement in hierarchical superstructures. Therefore, this review will focus on the design principles of SCPs by discussing supramolecular construction strategies and state-of-the-art functional applications from mechanical toughening to sophisticated functions such as dynamic adaptivity, shape memory, ion transport, Current challenges and further opportunities are discussed to provide an overview of possible future directions and potential material applications.
以各向异性的非晶域和晶域为基本骨架的半结晶聚合物（SCP）广泛存在于从天然产物到合成聚合物的各类物质中。化学性质不相容的硬相和软相的结合赋予了其独特的热性能和机械性能。进一步引入作为非共价相互作用晶相和软动态交联位点的超分子相互作用，可以与共价聚合物链协同作用，从而在分级超结构中实现有效的能量耗散和动态重排。因此，本综述将通过讨论超分子构建策略以及从机械增韧到动态适应性、形状记忆、离子传输等复杂功能的最新功能应用，重点关注SCP的设计原则。同时还将讨论当前面临的挑战和进一步的机遇，以概述未来可能的发展方向和潜在的材料应用。
