Microfluidic reactors have remarkably promoted the synthesis and investigation of advanced nanomaterials due to their continuous mode and accelerated heat/mass transfer. Notably, segmented microfluidic flow reactors (SMFRs) are an important class of microfluidic reactors that have been developed to accurately manipulate nanomaterial synthesis by further improvement of the residence time distributions and unique flow behaviors. This review provided a survey of the nanomaterial synthesis in SMFRs for the aspects of fluid dynamics, flow patterns, and mass transfer among and within distinct phases and provided examples of the synthesis of versatile nanomaterials via the use of different flow patterns.

微流控反应器因其连续模式以及加速的热/质量传递，显著地推动了先进纳米材料的合成与研究。值得注意的是，分段微流控流动反应器（SMFRs）是一类重要的微流控反应器，通过进一步改善停留时间分布和独特的流动行为，已被开发用于精确控制纳米材料的合成。本文综述了SMFRs中纳米材料合成在流体动力学、流动模式以及不同相之间和相内的质量传递等方面的情况，并给出了通过使用不同流动模式合成多种纳米材料的实例。
