**4.3 Flexible and stretchable display**

Flexible and stretchable display is the utmost need of the future electronics, and graphene is doing its job elegantly in this domain [38]. Beside remarkable properties, mineral resources consider so far unsuccessful for rigid components, and this limits their utility. On the contrary graphene and its variants are emerging candidates in flexible as well as in stretchable electronics [39]. Various distinguished traits ensures its availability in modern devices like LEDs and for conversion and in energy storage devices as well as shown in **Figure 7**.

On the contrary, most utilized material like Indium tin oxide, exhibits wide range of discrepancies such as high corrosion rate, much higher refractive index, and less economic feasibility etc. [40].

#### **4.4 Energy storage devices**

Application for energy storage devices also attributes to graphene. This is due to the Ultimate reduction in restacking of graphene sheets specifically when interacting with metal oxides. The prime logic for graphene's utility in this arena of energy storage devices is its highly conductive nature, especially when it comes to interlinked network. Mechanically as well as electrochemically stable along with porosity in the structure all proves its significance in this current domain of application. Photovoltaic cells, batteries and fuel cells entirely rely on energy storage devices. For supercapacitors, ensuring material for electrode is graphene's job. The process of dysenetization can also be performed by these electrode material [41].

#### **4.5 Corrosion coating**

Graphene inherently behaves as a corrosion resistant, whenever coated. Penetration power constitutes a substantial increase in polymer coating. However, graphene enters along thickness of coating into the medium, and anti-corrosion process initiates right after the entrance of graphene to the interface. Carbon atoms in graphene exhibits sp2-hybridization, comprising high electron density, that renders all incoming corrosion molecules [22]. Hence, such kind of fascinating structure in graphene leads to its durability. In addition, graphene holds an excellent protection shield in the infiltration stage due to its capability of prolonging the path. Therefore, durability as well as corrosion resistance can be enhanced remarkably.
