Abstract A customized droplet-based microfluidic reactor was fabricated for the synthesis of silver nanoparticles (Ag NPs) using silver nitrate (AgNO3) and branched polyethyleneimine (BPEI) as a precursor and a reducing agent, respectively. The effects of static mixing, temperature, and the volumetric flow rates of AgNO3 and BPEI on the particle size were investigated. The use of a static mixer and the optimization of the reaction temperature enhanced the monodispersity of the Ag NPs. In addition, the size of the Ag NPs was manipulated by changing the flow rate ratio of AgNO3 to BPEI at 60 °C for 60 min.

基于液滴形成的定制微流体反应器用于合成单分散银纳米粒子

摘要 以硝酸银 (AgNO3) 和支化聚乙烯亚胺 (BPEI) 为前驱体和还原剂，制备了定制的基于液滴的微流体反应器，用于合成银纳米粒子 (Ag NPs)。研究了静态混合、温度和 AgNO3 和 BPEI 的体积流量对粒径的影响。静态混合器的使用和反应温度的优化增强了 Ag NPs 的单分散性。此外，通过改变 AgNO3 与 BPEI 在 60°C 下 60 分钟的流速比来控制 Ag NPs 的尺寸。
