Introduction
Graphene is first isolated at the University of Manchester in 2003 by a team led by Andre Geim and Kostya Novoselov. It is the first single-layer material ever discovered. It is also the strongest—200 times stronger than steel.
Graphene is a material, which extracted from graphite and is made up of pure carbon, one of the most valuable elements in nature and which we find in daily objects like the lead of a pencil. Graphene stands out for being tough, flexible, light, and with a high resistance.

Graphene is an allotropic form of carbon which consist of a single layer of atoms arranged in a hexagonal lattice nano structure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds.
Each atom in a graphene sheet is connected to its three nearest neighbors by σ-bonds and a delocalised π-bond, which contributes to a valence band that extends over the whole sheet.
Uses of Graphene
1. It is used in water filtration to produce Better Quality Water.2. Graphene is used to make Touch Screens for Paper-Thick Mobile Phones
3. Graphene is used to make Headphones
4. It is used to produce Super-fast Charging Batteries
6. Due to its flexibility it is used in different Wearable Technologies
7. Graphene Membranes are used for Fresher Food & Air products
8. Graphene is used in Coating of different materials
9. Medical Sensors made of Graphene for Early Disease Detection
10. Graphene is used in Hard Drives
11. Graphene is use to make Shoes and Helmets
12. Conductive Ink by Graphene
Graphene is a blessing for us due to its characteristics. It has a wide range of applications that make our lives easier. As mentioned above, in our daily life, it can be used in safety labels, headphones, racquets, smartphone, batteries, and there are many more. From the science to the world and the daily lives, cutting-edge technologies can be transferred by using the unique graphene products from Nanografi.
Drawbacks of Graphene
- Creation of high quality graphene is expensive and complex process.
- Great conductor of electricity, graphene cannot be switched off. Scientists are working on rectifying this.
- In order to grow graphene, toxic chemicals are being used at high temperatures. Due to this it exhibits some toxic qualities.
- Graphene has ultra-sharp edges that can easily pierce cell membranes, allowing it to enter into the cell and disrupt normal functions.
- One of the obstacles that needs to be overcome is how to make sheets of graphene large enough and pure enough to be useful. Any non-carbon atoms can disrupt the perfect hexagonal pattern of graphene.
These are just, but a few of the ‘wonder material’s’ advantages and disadvantages and since the material is still in the research stage much more is yet to be revealed.
Superb 👌💥
