Graphene: The Material That’s Going To Change The Future

Table of Contents (click to expand)

Graphene is a material that has the potential to change the future. It is the thinnest and lightest material in the world, yet is roughly 300 times stronger than steel. It conducts electricity faster than copper and conducts heat better than a diamond. It is bendable, stretchable, transparent, and waterproof. It prevents corrosion and rusting. It is even biodegradable. Finally, and perhaps most importantly, it is derived from one of the most commonly found household items.

We have all seen countless sci-fi representations of our future. Hoverboards, sleek electronics, self-tying shoes (yes, Back to the Future II, I’m looking at you)… all of them seem like impossible predictions, but there is always something coming next, right?

While these things may seem a bit far-fetched, there is one savior that can pull us from our static misery and propel us into the future. There is one perfect material that can make all our dreams come true. It is the thinnest and lightest material in the world, yet is roughly 300 times stronger than steel. It conducts electricity faster than copper and conducts heat better than a diamond. It is bendable, stretchable, transparent, and waterproof. It prevents corrosion and rusting. It is even biodegradable. Finally, and perhaps most importantly, it is derived from one of the most commonly found household items.

Our hero’s name is Graphene.

Graphene 101

We’ve been aware of graphene’s existence since 1859. After all, graphene is nothing but a single sheet of carbon atoms. Layers and layers of these sheets of graphene stack up to create graphite. Yes, the same thing used in pencil lead.

However, graphite is brittle, common, and generally unimpressive. In that case, what makes graphene so special?

The power of graphene is that it is the first two-dimensional material known to humankind. Just to be clear, I mean two-dimensional from an electron’s perspective, not ours. To us, graphene is three-dimensional, as it DOES have a thickness of one atom. However, to an electron passing through it, graphene is a two-dimensional highway. Unlike 3D graphite, where electrons can move in any which way they want; in two-dimensional graphene, their movements are restricted to just one direction.

Almost 150 years were spent trying to isolate graphene from graphite. This consisted of 150 years of strenuous lab experiments and absolutely no results to show for the effort. This led to the idea that two-dimensional materials must be unstable at room temperatures.  The scientific world seemed to have abandoned graphene.


Then, along came two scientists with the names of Andre Geim and Konstantin Novoselov. They created graphene using (and I’m quite serious when I say this)… scotch tape. Yup, you got it. 150 years of scientific research and no one tried using scotch tape to separate graphene. Embarrassing? Quite.

Needless to say, the duo won a Nobel Prize for this *ahem* remarkable experiment.

tnbszNow, why can I so confidently claim that graphene will be the harbinger of change? Well, let me give you a few potential uses for graphene.


One thing that seems to restrain all technology is batteries. Batteries are essentially the party poopers of the technological realm. They drain away, they die off, they burst, and they are impossible to recycle. However, the time has come to say goodbye to these cumbersome batteries, because graphene is here!

As mentioned earlier, graphene is a flat sheet of atoms where electrons can zoom around quickly. Because of its immaculate hexagonal matrix, graphene offers almost no resistance, making it the best electrical conductor that we have ever discovered. In fact, graphene supercapacitors would take roughly 5 seconds to charge your phones!


Graphene would also revolutionise solar energy! This remarkable material can be used to create stronger and better solar cells that are easier and cheaper to produce than the silicon ones we use today.

Speaking of replacing silicon, graphene can also be used to make microchips. These graphene microchips would function at frequencies 10 times that of silicon. And guess what? Those annoying heating problem your computers always seem to experience? Graphene would completely eliminate the issue.

tnbxhAnother novel way to use graphene is to deliberately misplace a single atom. Why would anyone poke a hole in graphene’s two-dimensional perfection? To use it as a sieve, obviously! By removing a single atom, you leave space for a single proton to pass through the graphene membrane. Now, which element has just a single proton? Hydrogen, of course! The same hydrogen that can now easily be used to make hydrogen fuel cells. This is a dream come true for renewable energy enthusiasts.

Purifying Water

Graphene is also hydrophobic! It would cling on to other materials, but let water pass through without any problem when micro-pores are made in it. This property of graphene could be used to purify contaminated water and could also be useful in hydraulic fracking. Graphene oxide has even been known to separate radioactive material from water.  Dangerous and risky tasks like cleaning up oil spills could be completed much more easily with graphene nanotechnology.

Potable water is growing scarcer by the day. One possible solution has been the desalinization of seawater. Graphene would speed up this process to be 2-3 times faster than the commercial desalinization technologies in use today. Say goodbye to water scarcity forever!

No more water scarcity!


Two words. Graphene. Paint. Yes, ladies and gentlemen, graphene can also be used as paint! Not only will it keep your house corrosion-free and waterproof, but because due to its photosensitivity, it can even power the same house using solar energy! Because of the immense potential of graphene as a conductor, the entire house can be used as an interface! TV on your ceiling? Gaming on the floor? Color-changing walls? The possibilities are truly endless.



Automobiles would also never be the same with graphene nanotechnology. Being the strongest and the most pliable material on earth, all automobiles could be made of graphene. Imagine how light those cars and jetplanes would be! They could run on solar energy that the car surface produces, or they could be recharged with graphene supercapacitors. Imagine electric cars that could get charged anywhere in a matter of seconds! The whole process would be completely eco-friendly too!


Graphene can also be utilized in the construction of incredible biosensors that can detect genetic diseases like Parkinson’s disease. Because of the thinness of the product, and the fact that it is essentially just carbon, graphene could also be used for tissue engineering. It would change the future of prosthetics as well. The more we think about this material, the more we realize that graphene may just be perfect?

Graphene is God’s gift to humanity


Graphene is a highly anticipated new advancement in the electronics industry. Touchscreens need sensitive conductors to be able to detect your touch. And as we have just learned, graphene is the best, most overachieving material in the world. So, not only can it replace silicon microchips and batteries in your electronic devices, it can also replace the external body. If that isn’t good enough, it can also make these devices transparent…and thin…and unbreakable. And flexible. And waterproof. And biodegradable. Not to mention, it can simultaneously generate solar energy to charge your phone or device. The possibilities are endless.

Meh. Graphene would make it flexible.

Graphene would also impact the speaker industry. A diaphragm made of a single sheet of graphene would be able to achieve the same sound quality produced by the most expensive of Sennheisers out there.


These applications are truly just a few of the ideas flying around the scientific, medical, technological, and commercial worlds. Scientists are discovering new uses for graphene all the time. From creating better gas sensors and improving collective health to developing actual invisibility cloaks and hover boards – graphene could do it all!

So, why isn’t graphene here already? I mean, graphite is found pretty much everywhere, right? Well, yes, but although making a small amount of graphene is a very easy task, producing it on an industrial level is a whole different ballgame.

However, don’t you worry! Graphene research is going full speed all over the world. In fact, the global market for graphene reached $9 million in 2014! It’s going to be here soon! The future is almost here.
