Carbon comes in many forms like lead, graphite, as well as in the form of diamonds. Initially, there were only few forms of carbon like diamond, graphite, and amorphous carbon but then few more forms were discovered like carbon nanotubes and fullerenes and it is then that Graphene was first introduced. Graphene is a honeycomb grid made up of carbon atoms and now in all initial forms of carbon, grapheme is the highly used metal like bonded on top in the form of graphite forming lead of the pencil, rolled into carbon nanotubes or folded in fullerenes.
Graphene is known as the two-dimensional metal as it extends only in length and width and is found to be emerging as one of the most super powerful and efficient nanoparticles as they exhibit some excellent and unique properties which make them totally different. Graphene is prepared by many processes and different methods produce different kinds of grapheme having variant qualities which may also cause defects, lead to impurity, structural disorders and wrinkles in graphene sheets.
Preparation
There are various methods to produce Graphene. Graphene is prepared with many toxic metals which lead to generation of many hazardous wastes leading to pollution and harm to environment. However many environment friendly approaches needs to be developed for such production.
Currently the various techniques used in production of Graphene are micromechanical cleavage, chemical vapour deposition, liquid phase exfoliation of Graphite, unzipping of carbon nanotubes and many more. Continuous and regular efforts are made by big industries, R&D institutes, universities and companies as large scale production is needed and so that the cost to buy graphene is reduced and high quality graphene is produced.
Properties inducing people to buy Graphene
1. People are coming with such argument as portraying Graphene is the strongest material available.
2. It is naturally the lightest metal and super electrified and super-conductive.
3. It exhibits super high speed of circuitry, good flexibility, and the thermal ability is incomparable.
4. This carbon allotrope also helps in improving the use and efficiency of other materials available.
5. Graphene is chemically stable also.
Thus the above promising qualities make graphene highly useful in various electronics of next generation as they have mechanical flexibility as well.
Buy low-cost Graphene and put to following Applications:
Graphene is used in making batteries which makes them cheap and highly conductive.
Industries buy graphene to use in the production of promising solar cells which makes them cheap, lightweight and flexible enough.
People buy low cost graphene made bio-sensors which help detect diseases as well as explosives.
Graphene is used in making of transistors and interconnects.
Researchers have evolved that buying highly conductive graphene for telecommunications application is also very useful as it proves to be at an advantage of photonics application.
Coating is another useful application of Graphene.
Graphene loudspeaker, EMI shielding, graphene based photothermal agents to kill bacteria are some other useful ways.
