There’s a key material that definesevery generation, from the bronze age and iron age to the recent silicon age.As for the near future,many scientists are claiming it will be the graphene age.
In 2004, Andre Geim and Konstantin Novoselovisolatedthe honeycomb-shaped layer of carbon atomscalled graphene. In their experiments, the two discovered that ithad amazing properties, so much so that it surpassed the best-known materials of the modern world. Because of this, their groundbreaking work was lauded, and they received the 2010 Nobel Prize in Physics.
But, what exactly are these properties? The following are some examples.
With a single layer at only an atom thick, or around a billionth of an inch in height, graphene is the thinnest material to ever exist. A graphene supplier can reshape this two-dimensional surface to create other materials, such as:
Fullerene: This is made by cutting and folding the sheet into a spherical shape.
Carbon Nanotube: This is created by rolling up the sheet.
Graphite: This is when sheets are stacked on top of each other (around 3 million layers).
High opaqueness comes with being a mono-layer atomic sheet. It absorbs only 2% of passing light, and lets the remaining waves pass through.
Despite its extreme thinness, graphene is really tough. In fact, it has an intrinsic strength of 130 gigapascals, which is 100x more than steel. Not only is it the world’s thinnest, but it’s also the strongest.
The products of graphene suppliers are in great demand because of their impressive thermal and electrical conductivity. Their resistance to electric current is among the lowest at room temperature, making them 35% more efficient than copper.
Graphene’s ability to transfer energy is also 5 times better than the metal. This ranks it among the best thermal conductors, along with the likes of diamond.
Additionally, it has the highest electron mobility out of all known materials. The charge can have a theoretical velocity of 200,000 sqcm per second, which is almost 100x faster than silicon.
Another puzzling property of graphene is its flexibility. Its original form can be stretched and bent by up to 25%,butit’s also extremely stiff at the same time. Its mechanical measurement of material solidity, or Young’s modulus yield, is at 1.0 TPa (terapascal); this means it’sas rigid as diamond.
Graphene is lighter than aluminum but tougher than steel and more elastic than rubber but harder than diamond. It’s also the thinnest, strongest, and most conductive material known of today. With these, it’s understandable why scientists consider it the key to the future. If you’re interested in learning more about it, contact a graphene supplier today.
