English Abstract

Graphene nano-sheets were prepared via modified chemical exfoliation route and utilizing graphite as starting material.

The employed preparation route ensured simplicity, short preparation time, room temperature preparation, and low cost.

The graphite was first purified chemically, and then exfoliated via ultra-sonication assisted chemical treatment to produce exfoliated graphite (EG).

This process was followed by thermal irradiation that leads to the formation of graphene after centrifugation process.

Atomic force microscope (AFM), scanning electron microscope (SEM) and Raman spectroscopy were used to characterize the prepared graphene sheets.

It was shown that the prepared graphene has trend to form hexagonal shaped sheets with wrinkled morphology.

The resultant thickness of few layers graphene stacks is about (3.34 nm) with large sheet diameter of about (97.44 nm).
