由于嵌段共聚物（BCP）在各种应用中的广泛应用，控制嵌段共聚物（BCP）的自组装行为是许多研究重点的焦点。虽然BCP分子量、体积分数和化学特性是确定其形态的关键热力学参数，但该领域的一种新兴方法是通过原位反应诱导BCP特性的变化，这提供了从单一母体聚合物获得多种形态和域尺寸的途径，以及能够形成可能难以获得的亚稳态形态。这项工作提供了一个集中的审查关于当前状态的反应诱导的形态控制BCP在溶液和固体状态。此外，我们提供了一个前瞻性的观点，了解和利用反应工程来操纵和推进BCP自组装的未来机会。© 2023工业化学学会。
Controlling the self‐assembly behaviors of block copolymers (BCPs) is a focal point of many research thrusts due to their broad use in various applications. While BCP molecular weight, volume fraction, and chemical identities are key thermodynamic parameters to determine their morphology, an emergent method in this area is through reaction‐induced changes to the characteristics of a BCPin situ, which provides access to multiple morphologies and domain sizes from a single parent polymer, as well as enabling the formation of metastable morphologies which may be difficult to attain otherwise. This work provides a focused review about the current state of reaction‐induced morphology control in BCPs in both solution and solid states. Furthermore, we provide a forward‐looking perspective on the future opportunities of understanding and employing reaction engineering to manipulate and advance BCP self‐assembly. © 2023 Society of Industrial Chemistry.
