Publication date: 25 July 2018Source: Journal of Industrial and Engineering Chemistry, Volume 63Author(s): Cheol Hwan Kwak, Sung-Min Kang, Euiyoung Jung, Yuvaraj Haldorai, Young-Kyu Han, Woo-Sik Kim, Taekyung Yu, Yun Suk HuhAbstractA 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.Graphical abstract
