Abstract

In this study, we presented a droplet-based microfluidic system for synthesizing three-dimensional (3D) graphene structure, called graphene popcorn. The droplets that were obtained by varying the flow rates and the concentration of graphene oxide (GO) solution were incubated in the furnace for rapid evaporation, resulting in the reduction of the GO as well as the aggregation of GO to form the graphene popcorn. The size of the 3D graphene popcorn could be controlled by the flow rate of the oil phase, and the aggregation degree was tuned by the GO concentration.
