General description

• Thickness: <3 layers.
• Lateral size : 0.5-5 μm.

Graphene is a single-atom-thick sheet of hexagonally arranged sp2-bonded carbon atoms. It can be prepared by various methods, such as mechanical exfoliation of graphite, micromechanical cleavage, arc discharge process, and chemical vapor deposition. Owing to its exceptional properties, it finds application in the fields of flexible electronics, biosensors, solar cells, anti corrosion coatings and drug delivery systems.

Application
Graphene can be used as a base material for flexible electronic devices due to its super electrical conductivity and large surface area. Graphene-based flexible electrodes show significant improvements in energy density and power density.

Graphene/polyaniline nanocomposites- modified electrodes can be used for the determination of heavy metals.

Heat-treated graphene nanosheets can be used to prepare solid adsorbents for rapid and selective CO2 capture applications.
