聚合物结晶领域的大多数研究活动都集中在本体、溶液或薄膜上。液/液（L/L）界面提供了另一个富有洞察力的平台来操纵长链聚合物的结晶。本综述将讨论受 L/L 界面影响或限制在 L/L 界面附近的聚合物结晶。首先讨论聚合物共混物和溶液，因为潜在的液-液相分离 (LLPS) 会产生与结晶强烈耦合的 L/L 界面。这将继续讨论利用平坦的空气/水界面，其中快速动力学提供了调整晶体结构和结晶的独特机会。然后，重点将转移到限制在弯曲 L/L 界面处的聚合物结晶，其中结晶过程同时受到界面化学和动力学、液滴内的 LLPS 以及这种弯曲环境中的限制的影响。通过操纵这种不同的参数空间，可以获得许多新颖的晶体和混合纳米结构。
Most of the research activities in the field of polymer crystallization have been focused on bulk, solution, or thin films. Liquid/liquid (L/L) interface provides another insightful platform to manipulate the crystallization of long chain polymers. This review will discuss polymer crystallization influenced by or confined near/at L/L interfaces. Polymer blends and solution will be first discussed as the underlying liquid‐liquid‐phase separation (LLPS) generates L/L interface which strongly couples with crystallization. This will continue into a discussion of utilizing flat air/water interface where the fast dynamics offers a unique opportunity to tune crystal structure and crystallization. The focus will then be shifted to polymer crystallization confined at curved L/L interface where the crystallization process is simultaneously influenced by the interface chemistry and dynamics, LLPS within the droplet, and the confinement in such a curved environment. Manipulating this diverse parameter space has allowed the attainment of numerous novel crystalline and hybrid nanostructures.
