Phone loaded in 5 seconds, retractable tablet ... Here's what you can graphene - Dziennik.pl

decided to check what are the possible applications of graphene – a material whose last name is inflected by all instances in the context of hope for breakthrough engineering solutions. Ordered them in alphabetical order. But the task we have set ourselves was also an attempt to explain this, but it really is a new structure produced in Poland. The assumption was this: the simpler, the better.

10 cm across Polish

– Graphene is a carbon – explained in an interview with Zygmunt dziennik.pl ?uczy?ski from the Institute of Electronic Materials Technology. I indicates that it occurs in many forms.

– It may be that the smoke in the oven, and one that with this furnace sometimes we extract as carbon black, but that’s not all. Coal after all, is also a diamond or carbon fiber, for example. The latter is an extremely powerful and flexible thin niteczki used even in poles athletes – is calculated.

Graphene is at the very symmetrical structure, and its shape resembles a collection of hexagons or – as some – honeycomb. Is flat – has only two dimensions, and its thickness is one atom, the researchers argue. Therefore, it can not be seen with the naked eye.

With adhesive tape on graphene

Methods for obtaining graphene are few. Poland, which started its commercial production, uses few, and the cost of the main raw material is virtually none. It turns out that it may be propane or butane, which is used in gas stoves.

interesting is the fact that Andrei Geim and Konstantin Nowosio?ow, Nobel Prize winners, who in 2004 discovered graphene, first adhesive tape stick to lumps of graphite. – detaches particles of graphite, then you attach another tape to this tape, break off, and so a few thousand times. Until they reached the very thin flake invisible to the naked eye – says the director of the Institute of Electronic Materials Technology.

Now the demand for graphene is estimated at less than 500 tons. In 2017 years has come to one thousand, and three years later, close to 3 thousand. tons.

use of graphene from A to Z

And as ink

already appeared grafenowy ink, which is to allow to print conductive materials. Not only that they will be flexible and durable, it is also cheap and durable. Further details at this stage were not disclosed.

B as batteries

Graphene can also be used in supercapacitors. This batteries, which are very slow to unload and load as quickly, which is of great importance in the case of eg electric vehicles. Now they need to be recharged often 6-10 hours, and yet could be for example 30 seconds.

But you can also imagine a situation that will be used in the engines of buses. The driver rides around town four hours, and when it stops at the loop for lunch, then these 15 minutes is sufficient also to re-charge the supercapacitor.

D as the Dreamliner

Graphene as a construction material? It is also possible that the more that can be combined with other materials, including metals. This would be such a breakthrough in the construction of aircraft, which is the case so far was a metal-carbon composite.

Replacement of various forms of carbon graphene could improve not only the parameters used in this example, resistance to impact, but also reduce their weight by at least a few percent. You have to remember that in this industry every kilogram of matter – airlines wondering because whether or not to paint their planes. If you do not, the machine corrode, otherwise – across the Atlantic driving around tons of paint, instead of hundreds of passengers.

F as paint

One idea involves also add it to the paint, which is painted pipelines, oil and gas, and fuel tanks in cars. Thanks grafenowi would not be possible accumulation of electric charges, which often – when I appeared spark – led to the spread of failures and fires.

I like the iPad

batteries using graphene could also be mounted in smartphones and other mobile devices. They loaded the full lasted less than 5 seconds.

K as a computer

Accelerate your computer up to 500-fold? Nothing easier, because the graphene almost without any obstacles conducts electricity. As a result, it could completely squeeze silicon-based technologies.

M as machines

But graphene can also be used in environmental protection. Sensors made from it can capture even a single molecule of harmful substances.

About as dressing agents

antiseptic properties of graphene may mean that it could be used in wound dressing, especially those that applied to the open wound. In addition, the fact that the structure of kills bacteria, wyd?u?a?by time of dressing change. So far, attempts to sterilize bandages, so as not to pass on the additional bacteria, which has not always proved effective.

Besides graphene could be used in food packaging – it would keep them fresh longer.

P as wires

If we could

copper or aluminum used in conjunction with the graphene in electrical cables, for example high-voltage cables, to improve their conductivity eclectic. This can translate into savings of billions of zlotys respectively, euro, dollars, scientists estimate.

R as cancer and its treatment

Preliminary studies conducted by the University of Agricultural promising. Tumor cells (glioma – are carried out on the sample) die and leave no harmful residues exceptionally, causing inflammation and often leading to death. All thanks to the fact that graphene is surrounded by a cancer cell and prevents it from contact with the environment.

S as window

But graphene – imperceptible to the eye – can also cover the glass in the car, including the front. Not only that it will be very strong, it can also be used as a touch screen. Moreover, when connected to electricity, the glass heats up and will not for example evaporate. Intensive testing in this area is already such as Volkswagen.

T as tablet

The future is also flexible electronics and do not need to wait for her ten years. For two or three years may arise screens rolled in a roll or eg worn as bracelet. They could take any shape. Leave to rest carriers worn under the arm, large flat objects resembling the shape of a box or cube, even the thinnest.

in the water

Although

graphene is impermeable to gases, it may be permeable for water. As a result, for example, is used in filters for water – its desalination. Such tests already carried out concern Locheed-Martin.
