Convert Polymer Self‐Assembly Nanostructures into Target Functional Materials: An Art of Embattling Molecules

Abstract Material design based on the assembly of functional units has demonstrated tremendous technical and commercial potential. Among others, polymers are identified to be an ideal building block due to their abundant functional groups, high programmability, and great biocompatibility. In this review, introducing recently developed advanced materials enabled by rationally designed polymer self‐assembly are focussed. The working principle of typical intermolecular interactions to shape nano‐patterns and structural heterogeneity is first explained in detail. Following that, methods to prepare advanced materials and their characteristic properties are discussed. The superior performance of polymer assemblies renders numerous potential applications in ultra‐tough devices, soft robotics, electronics, sensors, and biomedicine. A brief account of representative examples is highlighted and a perspective on this field is provided at the end.
