Droplet-based 3d Graphene Structure Synthesis

چکیده
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.

In this paper, we present a simple method for preparation of graphene-ZnO nanocomposites (G-ZnO). The method is based on thermal treatment of the graphene oxide (GO)/ZnO paste which reduces the graphene oxide into the graphene and leads to the formation of the G-ZnO nanocomposite. The structure, morphology and optical properties of synthesized nanocomposites are characterized with XRD, FESEM, F...

متن کاملA novel semiconductor compatible path for nano-graphene synthesis using CBr4 precursor and Ga catalyst
We propose a novel semiconductor compatible path for nano-graphene synthesis using precursors containing C-Br bonding and liquid catalyst. The unique combination of CBr4 as precursor and Ga as catalyst leads to efficient C precipitation at a synthesis temperature of 200 °C or lower. The non-wetting nature of liquid Ga on tested substrates limits nano-scale graphene to form on Ga droplets and su...
