Graphene
Graphene the material of Future
It is the strongest
material ever tested yet. It is super-capacitive, conducts electricity better
than silver, 200 times stronger than steel, yet is ultra light and can be
molded into any shape. These properties make graphene the material for our
technological advancement in space travel, architecture, efficient energy
transfer and much powerful computers. If not this then atleast we can make the
Captain America shield out of it.
It gained the hype in
2013 when scientist used graphene as an electricity source for an bulb and the
results were amazing, with charging for mere seconds graphene was able to gains
electric current which was able to make the bulb light up for minutes.
But then came the
downfall, graphene faded away not because it was a hoax but because we were
having difficulties making it. We were able to make very small amounts of
graphene with very difficult processes. Hence it was not studied on a large
scale, then in 2015 a study came out in which they literally grow the graphene lattice
on a copper base. But from that method they could only grow a sheet of 8x13mm,
which was not so great.
Then in 2017 we had a
promising method described in study by Nature and Communications stated that
they could make graphene in a single step, by heating soya bean oil to 800
degree C on a nickel foil, this reduced the manufacturing cost by 10 times but
scaling was still an issue as the largest sheet created was the size of a
credit card.
Then finally again in 2017 a physics professor patented a
high yield method of making graphene, it is scalable, cheap, does not require a
special laboratory and does not require any harmful chemicals. In this method
they literally explode oxygen and acetylene, acetylene gives the required
carbon which makes itself into graphene in the heat of the explosion. But the
resultant graphene is not in sheets which are ready to be industrially used but
they are made in chucks which are huge when compared to other methods but the graphene
made is not high quality.
