What Is "Graphene" and its advantages


scientists are always trying to render infinitesimal energy from a material that common man can never comprehend of. But it's always a good thing, to know what exactly is going on in our little world of pure wonder. So I'm going to give you some information on something that just might change our world right before our eyes. "Graphene". In simple words Graphene is a 'single layer of carbon sheets; Just imagine the graphite in your pencils.. the smallest and the singular layer of graphite is "Graphene". It's a sheet of pure carbon that is one atom thick. It is amazing how such a simple substance actually holds such impressive properties: 

• First created 2D material 

• One of the strongest materials 

• Lightest and thinnest material possible

• Very flexible and transparent

• Excellent electrical and heat conductor

• Graphene can enhance the current carrying properties of devices 

• It can be stretched to about 20% without being damaged 

• Graphene can be used to manufacture nanoscale templates based on its geometry
Electrical Properties Of Graphene: 

The flat hexagonal structure of Graphene offers relatively less resistance to electrons, which zip through it quickly and easily. It can carry electricity better than conductors such as copper and as well as Superconductors.

 Applications Of Graphene: 
• Batteries: Taking advantage of its conductivity and light weight Graphene can be incorporated in lithium-ion batteries to store 10 times as much power and charge 10 times faster and last longer as well. The batteries can also be made smaller. 

• Cell Phones: Touch Screens made with Graphene would be light and flexible, cell phones as thin as a piece of paper and foldable enough to slip into a pocket can be made. • Green Energy: Imperfect Graphene Allows positively charged hydrogen atoms or protons to pass through it, despite being completely impermeable to all other gases. 

• Bulletproof Armor: Graphene can also be used to build bulletproof vests. Sheets of Graphene absorb twice as much impact as Kevlar, it is super lightweight and much easier to wear as well. 

• Drinkable Oceans: Graphene could help to solve the world water crises. Membranes made from Graphene could be made that are big enough to let water through, yet small enough to filter out all the salts and impurities. 
• Solar Cells: When Graphene-coated Solar Cells are subjected to simulated raindrops, electricity is created. The salts contained within raindrops tend to dissociate into their component ions. And the positively charged ones are eager to interact with the negative ions in Graphene. This creates a potential between the two layers which renders electricity.
