5 Characteristics Of Graphene
Graphene is a type of material that is often counted as one that will revolutionize technology in the future. Check it out right now!
First, Graphene is a material produced by extracting superficial layers of graphite (the same used in pencils), abundant mineral on earth and one of the most common carbon allotropes.
Also, Graphene is composed of carbon atoms bonded to hexagonal crystalline structures using sp2 bonds.
These bonds repeat over a two-dimensional plane.
Graphene is considered the finest material in the world. It consists of a two-dimensional layer of carbon atoms arranged in hexagonal structures.
The chemical bonds between carbon atoms and graphene thickness give this element some wonderful physical properties.
Good examples are mechanical resistance, thermal and electrical conductivity.
Consequently, it has varied applications.
First, in 1947 physicist Philip Russell Wallace discovered and studied the principles of the material.
However, it was not until 1962 that German chemists Ulrich Hofmann and Hanns-Peter Boehm named the compound.
The name given was the result of the combination of the words “graffiti” and the suffix “-eno”.
Until 2004, Graphene was known only to the scientific community.
Scientists Konstantin Novoselov (Russian-British) and Andre Geim (Russian-Dutch), both from England, have changed that.
At the time, the two decided to test the potential of Graphene as a transistor, an alternative to silicon used in semiconductors.
Their studies made the material thinner and thinner until it was as thin as an atom.
Nevertheless, the structure was not damaged in its conductivity.
The discovery earned these scientists, six years later, the Nobel Prize in Physics. In 2010 alone, around 3,000 studies were published that prove the seemingly unlimited features of the Graphene.
Check out 5 features of Graphene
1 – World’s most conductive material
Firstly, it has a high conductivity.
This is because electrons move through Graphene with virtually no resistance and seemingly massless.
As a result, electricity is transported faster, more efficiently and more accurately than any other material.
Depending on what will be created with this material, the result can be surreal.
Have you ever imagined graphene cell phone batteries? Surely the devices would be charged in 5 seconds.
2 – Atoms with the naked eye
Initially, according to Rive University in Texas, the material is visible.
Even though it is the thinnest material in existence, it is only one atom thick.
Graphene absorbs only 2.3% of light, but if you put it on a piece of paper, you will be able to see it.
3 – Stronger than steel
Graphene is extremely strong despite being thin and light.
Moreover, it is the hardest element ever known, surpassing even the diamond.
For example, a 1 square meter graphene sheet weighs only 0.0077 grams but can support a weight of up to 4 kg.
4 – Flexibility, transparency and impermeability
On top of all this, the material has great elasticity despite rigidity.
It stretches up to 25% more than its length.
In addition, it is also the most waterproof material ever discovered. For example, even helium atoms cannot pass through it.
5 – Bi-dimensional
First, graphite is the three-dimensional version of carbon.
Graphene has very different characteristics since it is two-dimensional.
Studying the material in question shows how other materials can behave two-dimensionally.
Nevertheless, it is curious how they came up with this two-dimensional material.
This element was isolated using a roll of tape, a piece of pure graphite and a transistor made of Graphene.
Possibilities of Graphene
Firstly, the material is very easily malleable. It also works very well for technology products due to its features.
Consequently, it works for the internet, for example, making it much faster. Also, it works for the automotive, naval, aeronautics and production of much lighter and more economical vehicles.
It can also be used to manufacture of earphones, solar panels, contaminated water detox, saltwater filter, FM signal transmitter, chips and bionic devices.
Even the condom can be made of it.
Nevertheless, the biggest challenge for companies and developers is to make the production of the material commercially viable and large-scale.
