Block copolymers (BCPs) self-assembly has continually attracted interest as a means to provide bottom-up control over nanostructures. While various methods have been demonstrated for efficiently ordering BCP nanodomains, most of them do not generically afford control of nanostructural orientation. For many applications of BCPs, such as energy storage, microelectronics, and separation membranes, alignment of nanodomains is a key requirement for enabling their practical use or enhancing materials performance. This review focuses on summarizing research progress on the development of anisotropy in BCP systems, covering a variety of topics from established aligning techniques, resultant material properties, and the associated applications. Specifically, the significance of aligning nanostructures and the anisotropic properties of BCPs is discussed and highlighted by demonstrating a few promising applications. Finally, the challenges and outlook are presented to further implement aligned BCPs into practical nanotechnological applications, where exciting opportunities exist.

在自组装嵌段共聚物中开发各向异性：方法、性能和应用

嵌段共聚物 (BCP) 自组装作为一种提供自下而上控制纳米结构的手段，不断引起人们的兴趣。虽然已经证明了各种方法可以有效地对 BCP 纳米域进行排序，但它们中的大多数通常不能控制纳米结构取向。对于 BCP 的许多应用，例如能量存储、微电子和分离膜，纳米域的排列是实现其实际应用或提高材料性能的关键要求。本综述重点总结了 BCP 系统中各向异性发展的研究进展，涵盖了从已建立的对准技术、所得材料特性和相关应用等各种主题。具体来说，通过展示一些有前景的应用，讨论并强调了对齐纳米结构的重要性和 BCP 的各向异性特性。最后，提出了将对齐的 BCP 进一步实施到实际纳米技术应用中的挑战和前景，其中存在令人兴奋的机会。
