Why Graphene material of the future ?!!
Why Graphene material of the future ?!!
Graphene have very extreme unique features make it material of the future and magical material and be ideal to become the most important future material in a lot of fields, we can say this reasons in details:
1- Strength :
Graphene the strongest material in the world !! and It is about 200 times stronger than steel by weight So A sheet of graphene as thin as Clingfilm could hold the weight of an elephant. In fact, according to one calculation, an elephant would need to balance precariously on the end of a pencil to break through that same sheet.
The secret lay in graphene atomic building it an abundant mineral which is an allotrope of carbon that is made up of very tightly bonded carbon atoms organised into a hexagonal lattice very thin atomic thickness (of 0.345Nm).
So it expects to see graphene used as a layer in bulletproof vests, armor, aircraft skin, etc., and certainly not replacing copper flashing on roofs, cladding on cookware, etc.
2- Electronics :
Graphene has more effective than silicon the highest intrinsic mobility (100 times more than in silicon) and conducts electricity in the limit of no electrons so when to replace silicon by graphene have great feature more, and graphene one of few materials can create and modify in atomic scale so make it ideal to all IC manufacturing , so use graphene to create super microprocessor
, massive strange RAM
and flexible screen
Graphene bulletproof can stop bullet easily because graphene 200 times stronger than steel
This strength leads to Recent tests suggest that pure graphene performs twice as well as the fabric currently used in bulletproof vests, making it an ideal armour for soldiers and police, Professor Jae-Hwang Lee at the University of Massachusetts-Amherst devised a new miniature ballistics test to test graphene’s mettle. They used a laser pulse to superheat gold filaments until they vaporised, acting like gunpowder to fire a micrometre-size glass bullet into 10 to 100 sheets of graphene at 3 kilometres per second – about three times the speed of a bullet fired from an M16 rifle.
Researchers have been studying graphene as armour for some time, but Lee’s is the first paper to describe just how the material absorbs kinetic energy. Sound waves travel three times faster through graphene than they do through steel, which means material far beyond the impact point can quickly absorb and dissipate its energy – effectively slowing the projectile down and helping prevent its penetration. What’s more, the micro bullet methods Lee developed could be used to study other high-performance materials in extreme conditions.
4- Power :
Graphene can make turbines and solar panel gives more power by make wires in resistor turbines coils wires in make it resistant less so give more power for example if use copper instant aluminum wire give more power because of copper-resistant for less than aluminum and when use wire have graphene layer in it will give more power than copper because of graphene have less resistant than copper .
5- Electricity :
Graphene very thin atomic thickness give it the highest current density (a million times that of copper) at room temperature; Which means it can carry more electricity more efficiency, faster and with more precision than any other material.
Graphene plane will have super features and use less fuel
6- Mechanics :
Because of graphene it the most strongest material in the world sure a lot of mechanics parts to give it more power and save it work for more time will build using graphene cars , tanks , ships and especially in plane manufacturing and space industry so graphene more strong and less weight so make it use less fuel insure that good from all environment ( planes make about 13% of world pollution ) and make ticket cheaper to clients.
Graphene Roll Up to make Carbon NanoTubes (CNTs) and it enter in a lot of fields
Carbon NanoTubes (CNTs) have many used like Electronics parts, Biomedical, Electrical circuits, Electrical cables and wires, Actuators, Paper batteries, Solar cells and Hydrogen storage, and it usually made from graphene sheet that “roll up” make the nanotube.
Graphene will replace copper in nano sutures because electrical resistance in 40-nanometer-wide nanoribbons of epitaxial graphene changes in discrete steps. The ribbons’ conductance exceeds predictions by a factor of 10. The ribbons can act more like optical waveguides or quantum dots, allowing electrons to flow smoothly along the ribbon edges. In copper, resistance increases in proportion to length as electrons encounter impurities.
