摘要：当嵌段共聚物（BCPs）在可变形的乳液液滴内发生自组装时，受限效应可有效打破结构对称性，使BCPs聚集形成具有独特纳米结构和性能的多种纳米尺度粒子。另一方面，自组装BCP粒子可作为支架，通过共组装或原位沉积进一步引导功能无机纳米粒子（NPs）的空间排列，从而生成性能增强的多种杂化功能BCP/NP复合材料。本文总结了BCPs在乳液液滴内受限自组装以及NPs在所得BCP支架上空间排列的最新进展，重点从实验和模拟两方面讨论了油/水界面性质、受限程度、BCP固有性质、添加剂、pH值和温度等多因素对自组装BCP粒子纳米结构及NPs在BCP支架上空间排列的影响。

Abstract：When the self-assembly of block copolymers (BCPs) occurs within a deformable emulsion droplet, BCPs can aggregate into a variety of nanoscaled particles with unique nanostructures and properties since the confinement effect can effectively break the symmetry of a structure. On the other hand, the self-assembled BCP particles can serve as the scaffolds to further direct the spatial arrangement of functional inorganic nanoparticles (NPs) via co-assembly or in situ deposition, thus generating diverse hybrid functional BCP/NP composites with enhanced properties. Here, we summarize the recent progress in the confined self-assembly of BCPs within the emulsion droplet and spatial arrangement of NPs on the resulting BCP scaffolds. This feature article focuses on the influence of multiple factors, including the oil/water interfacial properties, confinement degree, intrinsic properties of BCPs, additives, pH value, and temperature, on the nanostructures of the self-assembled BCP particles as well as the spatial arrangement of NPs on the BCP scaffolds from both experiment and simulation studies.
