Graphene is characterised by its two dimensional (2D) material where carbon atoms are arranged hexagonally and possess sp 2 hybridization . Graphene nanomaterial is available in several allotropic forms, including graphene nano-ribbons, nano-sheets, nano-plates, and 3D graphene. Each of them established with incredible applications as all these form possess different properties. Graphene's electrical and quantum characteristics are still under investigation . The bond length of C-C atoms in graphene molecule is around 0.142 nanometre . The graphene molecule thickness is 0.335 nanometre while a diameter of graphene molecule is varying from few microns to several 100 μm . The discovery of graphene paved the way for fresh study into carbon materials. As a result, the Nobel Prize was awarded to British scientist Andre Geim and Russian scientist Konstantin Novoselov in 2010. Graphene possesses outstanding characteristics that set it apart from other materials. Graphene is the strongest substance that has ever been found. It has a Young's modulus of 1 Terapascal (TPa) and tensile strength of 130 Gigapascal (GPa) . Graphene also possess has electric conductivity as high as 6×10 5 S/m , thermal conductivity of approximately 3000 to 5000 W/m.K , high electron mobility 200,00 cm 2 /V.s . Due to two dimensional structure of graphene it also characterised by high surface area of approximately 2600 to 2630 m 2 /grams[55] . Graphene, a single layered hexagonal carbon atoms proven to be chemically stable at temperatures ranging from 400 to 500°C . Graphene is also characterized by exceptionally high mechanical properties, gas permeability, remarkable thermodynamic performance, excellent barrier properties, corrosion resistance etc. [62] [64] . This has been established that graphene's ultra-dense lattice of carbon atoms provides a hermetically sealed barrier that protects the material against corrosion while being so thin that properties of coated surface remains unaffected . Though graphene shows such excellent characteristics, due to its inherent re-stacking tendency, this novel material suffers from poor dispersion and formation of aggregation during coating preparation . Formation of aggregates and agglomerates because of strong Van der Waals' forces in graphene molecule . Enormous research is being conducted to improve its dispensability in coating medium. Graphene and its allotropes with necessary modifications are extensively employed in synthesis of polymeric coating due to its outstanding anti-corrosion properties. The anticorrosive properties are exhibited by graphene due to their lamellar structure. This plate like structure of 2D graphene creates highly convoluted pathways and prevent penetration of corrosive medium like oxygen or moisture from atmosphere to reach to underneath metal surface thus, protecting the metal from corrosion .
