• Graphene is a single layer of carbon atoms bound in a hexagonal shape. If the graphene in question is in another form, this will be specified. Two-layer or multi-layer graphene, for instance, are the other forms of this material.
• Graphene is an allotrope of carbon as diamond and graphite. To be more precise, graphene is composed of sp2-bonded carbon atoms and comprises a 0.142 nm molecule bond distance between its atoms.
• Graphene has three significant qualities: it is 100–300 times stronger than steel, it is the best known conductor in room temperature, and it is flexible.
• Graphene is the thinnest and lightest material known to humankind.
• Graphene is transparent.
