The development of synthetic methods for micro/nano materials with precisely controlled structures, morphologies, and local compositions is of great importance for the advancement of modern nanotechnology. The electrospray method is a “platform” approach for the preparation of a broad range of micro-/nanostructures; electrospray is simple and scalable. This review summarizes recent research on the micro-/nanostructures prepared via the electrospray route. These include spherical structures (e.g. simple, porous, Janus, and core–shell particles), non-spherical structures (e.g. red blood cell-like and spindle-like particles, multi-compartment microrods, 2D holey nanosheets, and nanopyramids), and assembled structures. The experimental details, underlying physical/chemical principles, and key benefits of these structures are comprehensively discussed. The effects and importance of nozzle design, properties of feeding solutions (e.g. concentration of solute, polymer additives, solvent/nonsolvent combinations), working environment (e.g. temperature and humidity), and types of collection media are highlighted.

通过电喷雾合成的结构化微纳米材料综述

对于具有精确控制的结构,形态和局部组成的微/纳米材料的合成方法的开发,对于现代纳米技术的发展至关重要。电喷雾法是用于制备各种微观/纳米结构的“平台”方法。电喷雾既简单又可扩展。这篇综述总结了关于通过电喷雾途径制备的微/纳米结构的最新研究。这些包括球形结构(例如,简单,多孔,Janus和核-壳粒子),非球形结构(例如红细胞状和纺锤状颗粒,多隔室微棒,二维多孔纳米片和纳米金字塔)和组装结构。实验细节,潜在的物理/化学原理以及这些结构的主要优点得到了全面讨论。突出了喷嘴设计的效果和重要性,进料溶液的性质(例如,溶质的浓度,聚合物添加剂,溶剂/非溶剂组合),工作环境(例如,温度和湿度)以及收集介质的类型。
