Introduction Gr consists of a single atomic layer of sp2 carbon atoms with a honeycomb crystal structure, which is one of the carbon in 2D and crystalline allotropes shape.
The Gr possesses an interesting structure, and has potential in various applications in conductive glasses [4], organic photovoltaic cells [5,6], field-effect transistor devices [7], and ultrasensitive sensors [8] due to its astonishing advantages in electrical properties.
Results and Discussion Based on basic chemistry knowledge, the chemical interaction between a sulfur molecule (derived from acid sulfuric) with graphene oxide layer is much more stronger than the van der waals force between distance p–p stacked graphene layers or between two sulfur molecules [11].
The result clearly shows that the crystal structure of graphene oxide is dependent on the stirring duration.
