Graphene – what is it about and what about graphene buy? This is an allotrope of carbon which is in the form of a two-dimensional, atomic, scale, hexagonal lattice where one atom forms each vertex. What’s more, it states for the basic structural element of the other allotropes, within graphite, charcoal, fullerenes or carbon nanotubes. It can also be said that an indefinitely spacious aromatic molecule, the ultimate case of the family of flat polycyclic aromatic hydrocarbons. Great article about graphene is here.

Another characteristic of grapheme is its band structure and Dirac cones effect of a grid on doping. Graphenes is widely used thanks to many different properties which I personally admire as it is used not only in science but also in fashion, when healing people and as it has many great properties it bears the unique power to hand out. Graphene is used mainly in technology which I read in here. And there is evident that more and more applications are being used graphene thanks to its great properties. However, there are some drawbacks as well, for example the price.
Graphene uses
Graphene can be used to enhance batteries, solar cells, sensors, material strength, electronic transistors. Each single year one could trace a great number of patents which are for the inventions from graphene tires to flexible cell phones.
The price of graphene
We all can say that graphene belongs to what can be named amazing material. And maybe you are asking yourself why. It is for the reason that it owns better electron mobility in comparison with the other metals. Graphene is flexible and at the same time it is also stronger than steel! But what one can´t predict is when and how the graphene will get to the market in huge volumes. And again and again – the most arguing spot is definitely its price.
For a quite decent prize, one can buy graphene at MST nano, or you might scour the internet yourselves in look for a bargain.
Expect to pay more for quality
What is very important according is the quality of the graphene which definitely affects the price of graphene. There should be mentioned that not all applications or gadgets need the highest material quality. E. G. graphene oxide powder (which states for graphene functionalized with oxygen with hydrogen) is not expensive and it is widely used when making a conductive graphene paper, for advanced composite and biotechnology applications, or even for DNA analysis.
On the other hand, it needs to be mentioned that grapheme oxide is not good enough for flexible touch screens, for batteries, smart window, LEDs or different advanced opto-electronic application.
Mechanically exfoliated graphene has the best physical properties and the price is matching
Well-known scotch tape technique has mechanically exfoliated graphene which is in small flakes (they are of high-quality). To the sought-after quality I can add mechanical strength. However, there are some disadvantages as they are small flakes for one square centimetre which is not enough for applications. And last but least, the price of it could be some thousands of dollars for one flake.
CVD graphene
This type of graphene is of good enough quality. It can be used nearly in each grapheme application. Its price associated with the production volume and costs of transferring from the copper substrate where it grows. The price of CVD is favourable in comparison with silicon carbide (which stands for significant semiconductor).
