Abstract

Nanomaterials have unique properties due to their nanoscale dimensions.
They can be used to design new technologies or enhance the performance
of existing processes. One of the most promising and remarkable
materials that play a vital role in nanomaterial technology is graphene
and its carbon family(Graphene/ Graphene Oxide (GO)/Reduced
Graphene Oxide (RGO). Different techniques areused forthe synthesis
and characterization of graphene.Top-down and Bottom-Up techniques
are the main techniques for graphene production. Thesesynthesis
methods play a dominant role in deciding the final properties of the
produced graphene.Different characterization methods are used to
identify the synthesized graphene.This work provides a comprehensive
review of graphene preparation and characterization techniques. A
new factor is proposed to describe the quality of the prepared graphene
according to the Raman spectroscopy, Scanning electron microscopy
(SEM) and X-ray diffraction (XRD) measurements.This graphene
quality factor (GQF) is used to compare the graphene produced using
several preparation techniques and prepared chemically RGO samples.
High-quality factor values of (0.9) were achieved for Chemical vapor
deposition (CVD) based graphene compared to lower quality factors for
other techniques. Chemically synthesized RGO samples were prepared
and had comparable quality factor values to other published works.
