Numerical study of the electrochemical exfoliation of graphite

Abstract

In this study, graphene was prepared using electrochemical exfoliation method. Numerical study of the exfoliation process of graphite was carried out using COMSEL Multiphysics 5. The homemade graphene was characterized using various microscopy, spectroscopy and X-ray diffraction techniques. The prepared graphene oxide consists of few layers of graphene. The numerical study showed that the concentration of sulfate anions was transported through graphite rod in the range (9.77 × 10−7– 4.58 × 10−5) mol/m3 and stresses distribution which resulted from sulfate anions interaction along the graphite rod in the range (3.43 × 10−8– 5.77 × 10−7) N/m2.
