摘要：将功能纳米粒子掺入嵌段共聚物胶束中可形成具有所需光学、电学和磁学性能的杂化材料。本文开发了一种通用方法，通过嵌段共聚物与纳米粒子在乳液中的协同组装制备超长纳米纤维。焓因素和熵因素共同促进了嵌段共聚物与纳米粒子的协同组装，形成均匀的杂化体。纳米粒子精确定位于纳米纤维的中心核内，纳米纤维长度可达数十微米。均匀的超长纳米纤维可作为构建集成结构或器件的构筑单元，用于纳米科学与纳米技术的基础研究和实际应用。

Abstract：The incorporation of functional nanoparticles within block copolymer micelles can form hybrid materials with desired optical, electronic, and magnetic properties. A versatile approach was developed to prepare ultralong nanofibers through the cooperative assembly of block copolymers and nanoparticles in emulsions. Enthalpic and entropic factors collectively contributed to the synergistic assembly of block copolymers and nanoparticles for the formation of uniform hybrids. The nanoparticles were precisely aligned in the central cores of the nanofibers which can reach tens of micrometers. The uniform and ultralong nanofibers may serve as building blocks for constructing integrated architectures or devices for fundamental study and practical applications in nanoscience and nanotechnology.
