(b) 10 Solution based methods have been widely used for the synthesis !"#$%&'()*+, of graphene from graphite or graphite oxide,1 using high energy '-%.", sonication for the exfoliation process in generating mono- or 2-8 multi-layer structures. However, the associated cavitation process can result in damage to the graphene,2 which can affect Figure 1. (a) Schematic of the vortex fluidic device (10 mm diameter 9,10 o 15 its properties.
