Graphene is quickly rising to become one of the most useful substances on Earth. It is an extremely hard substance, an excellent conductor of heat and electricity, and only 1 atom layer thick. Even better, it is as abundant as graphite, the black substance found in pencil leads, as graphene stuck together in many layers is in fact graphite.
But up until now, there had been a problem with this amazing material: its production. Obtaining some graphene is relatively easy: you get a piece a graphite from any pencil, and using some tape, stick and unstick it to the surface of the graphite continuously. This way, you will end up with a very small of graphene. This surprising method was discovered by two students at the University of Manchester: Andre Geim and Konstantin Novoselov, who won the Nobel Prize for Chemistry precisely for this technique.
The problem is that although this tape method works perfectly fine to produce some graphene, it’s not an efficient way to manufacture amounts large enough to meet the demand for this product. So scientists have been working non-stop to find a solution to their problem, and indeed they have found a very curious one.
Just as the original technique, its fairly straightforward. You just need some graphite, some water, soap and a blender. Now just add it all into the blender and turn it on. After a few seconds of work, you have produced a decent amount of graphene. The blades manage to cut between the layers of graphene in graphite and produce individual graphene.
The bright side of this process is that it produces 5 grams of graphene an hour, whilst previous methods produced only half a gram an hour. On the downside, however, is the fact that its not really as easy as this, and to get the best results you need to use more sophisticated substances and to get a decent amount the experiment would have to be scaled up.
It is still an enormous improvement compared to the previous methods that will for sure make this outstanding material more approachable, and all the technological revolutions it will bring closer to our reach.
