There are times in history when something big happens and you just know our lives are going to change. Edison and the light bulb, the personal computer and soon we may add Graphene to the list of history’s significant technological steps forward. It is not often something like this comes along, something which could be so ubiquitous and touch our lives in so many ways. So what is this new wonder material. Well it is basically one of the first two dimensional materials. It is a film of carbon atoms only one atom thick. This is a material so thin it is impossible to get thinner. Think of carbon fiber, but only one atom thick. Grapheneis one of the crystalline forms of carbon, alongside diamond, graphite, carbon nanotubes and fullerenes. In this material, carbon atoms are arranged in a regular hexagonal pattern. High-quality Graphene is very strong, light, nearly transparent, and an excellent conductor of heat and electricity. Its interaction with other materials and with light, along with its inherently two-dimensional nature, produce unique properties.
Before I get to all of the really cool things you can do with Graphene here is a short list of its properties.
So what can you do with this? Well to give you an idea if how strong it is you could take a 1 meter square piece of this material, one atom thick, weighing .77 grams, and make a hammock for your 4 kg cat. Yes, that is a little silly but think about it. This one atom thick material is strong enough to hold up your cat, but weigh as much as the cats whisker. Now to some more practical applications besides cat hammocks.
Because it is both transparent and conducts electricity you can say goodbye to the broken screens on your mobile phone. Also they will be much thinner and lighter Your phone will have a basically indestructible screen that weights basically nothing. Also it could be flexible enabling these kinds of devices to be integrated into clothes, or any other material you can think of.
Solar panels could be made Graphene due to it’s excellent transparency and ability to conduct electricity. Estimates show that using Graphene instead of Silicone could yield solar panels that at are 60% efficient.
A replacement for silicone in computer chips. Graphine has already been made into transistors and simple integrated chips. We could have smaller, lighter, faster computer chips….and they could even be flexible.
Desalinization – Studies suggest this material could outperform current processes in removing salt from water, thus solving water shortages in many parts of the world with cheap easy access to water.
Stronger, reinforced plastics. If you embedded it into plastic you can make it much stronger. In addition you could also make it conductive to electricity if you desire. Think fenders that are stronger than steel ones of today but also flexible. If you had a fender bender it would be harder to bend the fender in the first place but also it would simply pop back into shape. It would be lighter, and never rust.
Replace Kevlar bullet proof vests with Graphene. Lighter, stronger and safer.
So many applications from a single new substance makes the mind boggle. Graphene is starting to get some real attention and real world applications of it are being developed at a rapid rate. The public will start to see it in use in the next few years, and it is going to change things. You can get much more technical detail at the Wikipedia site.
Methods for the mass production of Graphene are still being developed. Oddly enough you can make some yourself at home with a pencil and some scotch tape. See the Video Below:
As mass production methods evolve we will see the use of this new material start to infiltrate our daily lives in ways we have not even thought of yet. A Nobel Prize in Physics was given to Andre Geim and Konstantin Novoselov in 2010 for their work with this material.
Geim and Novoselov extracted the Graphene from a piece of graphite such as is found in ordinary pencils. Using regular adhesive tape they managed to obtain a flake of carbon with a thickness of just one atom. This at a time when many believed it was impossible for such thin crystalline materials to be stable.
It is truly exciting to think about all the possible applications of this material. In a few years you will have some in your home, in your cloths, your cars, your life. Remember it and watch as it evolves, maybe you will even think of a new application for this wonder material.

Graphene is nothing but a carbon nanotube sliced open, and I suspect that the latter will make impact even more rapidly than the former. With the Rice University invention of a method for turning nanotubes into strong, flexible threads capable of conducting almost as much electricity as copper (even silver at proper purities), I expect that use to explode more quickly than the problematic graphene with it's edge difficulties and instabilities. Both will be huge in the long run. What I expect to see is carbon wiring replacing copper and other materials at everything from the internal chip level to electrical transmission, while nanotube threads add strength to most of the things you spoke of for graphene. Graphene paper will probably accomplish most of the structural things you noted, though specialized forms of lignin and cellulose derived from plants may cover part of that spectrum, again largely carbon based. Large sheets of atomically highly pure graphene will always be difficult to produce, and will usually require a substrate on which to operate, while nanotube threads require no such support and can be made by techniques similar to those for artificial thread extrusion in spinnerets.
As copper becomes more and more expensive and difficult to obtain, we will need carbon nanotube wires to fill many of its roles. They have a huge advantage for transmission lines in that they will not be endangered by EMP of any variety. Properly doped, carbon nanotubes can be highly conductive, semiconducting, or insulating, allowing entire wires to be made largely of carbon.
Your initial thesis, I believe is more than correct.
