Graphene- The Wonder Material!
Graphene- The Wonder Material!
1. What is grapheme?
Graphene is a single layer of carbon atoms, tightly packed into a hexagonal honeycomb lattice. It is an allotrope of carbon, existing in the form of sp2 bond atomic plane, with molecular bond length of 0.142 nanometers. Layers of graphene form graphite, spaced 0.335 nanometers apart. The separated graphene layers in graphite are held together by van der Waals forces that can be overcome during the graphene stripping process.
2. Graphene’s Properties
(1) The thinnest single-atom-thick.
(2) The lightest material.
(3) The strongest compound.
(4) The best thermal conductor at room temperature.
(5) The best electrical conductor.
(6) Absorption of light in the visible and near-infrared parts of the spectrum (PI alpha ≈2.3%).
3. Graphene’s uses
(4) Coatings, sensors, electronics and more
Graphene has many other promising applications: anticorrosive coatings and coatings, efficient and accurate sensors, faster and more efficient electronics, flexible displays, efficient solar panels, faster DNA sequencing, drug delivery, and so on.
4. Potentials of graphene
Graphene-powered supercapacitors store a lot of energy, making them easier to charge and discharge quickly. Because of its efficient and fast charging properties, graphene makes it easier to acquire and carry the devices that requires higher power.
Graphene-based battery alternatives have improved energy storage and improved performance through their lifetime of use and charging. The energy capacity and reliability of the battery are improved by adding two-dimensional materials to the battery electrode. Subsequently, the devices can be more efficient for a longer period of time and provide higher cost performance.
(2) Applying graphene for advanced technology
In 2016, Huawei, a china-based network, telecommunications and services company, revealed that it was trying to develop an innovative graphene-enhanced lithium-ion battery. The marketing pitch for the battery is that it can maintain function and run longer even at temperatures above the 50°C limit. Using a number of innovative technologies, Huawei battery ensures heat dissipation by:
As a great and fundamental building material, it seems that every industry can benefit from this new material. Time will tell what kind of impact can this “wonder material” can make, let us wait and see!
