What Has Happened to the "Miracle Material"
It all starts here, in the lead of a
graphite pencil. From this simple material,
graphene emerges, an ultralight,
flexible compound, stronger than steel, a
better electrical conductor than copper and, in addition,
transparent and impermeable to gases. That's why they
call it the "miracle material". Although
two decades have passed since its discovery,
graphene has not changed the world as many
predicted when it was discovered, but there are also
important advances. Stay, because before
you sharpen your pencil, I'll tell you in this video.
In 2004, these two scientists managed to isolate
graphene using a technique as simple
as placing adhesive tape on graphite.
Until you get one that is just one atom
thick. This earned them the Nobel Prize in
Physics in 2010 and unleashed the so-called “
graphene fever” among the scientific community. But
what is it about graphene that makes it so special?
This material is a very thin sheet of
pure carbon in which the atoms are arranged
in a hexagonal structure, like a
honeycomb. Thanks to its structure, graphene
presents a series of extraordinary properties.
As I told you at the beginning, it is 200 times
stronger than steel, it conducts electricity
excellently, it is extremely
light, flexible and, in addition, it does not pollute.
These features sound almost like science
fiction and could revolutionize industries and fields
ranging from technology to medicine. For
example, graphene could increase
the useful life of batteries tenfold and reduce their
charging times. Opening the possibility of replacing
current lithium batteries and changing the landscape
in sectors such as electric vehicles.
Plus, its flexibility makes it
ideal for ultra-thin,
rugged displays that could bend like
this sheet of paper. In construction,
graphene could improve the
thermal insulation of buildings, making them more
durable and efficient. And in medicine, lighter and more flexible
graphene prostheses are being investigated
, with the potential to create
artificial bones and muscles. But despite
initial enthusiasm from scientists and
technology companies, its use is still limited. You
may not have realized but most
cars, cell phones or a golf club
contain graphene, that is, the material is
having an impact on some products although it may
not be as visible to consumers. It is
found in high-end products:
such as electronic displays, sensors,
fast-charging batteries, and high-performance sports devices
such as helmets and rackets. It is also
used in some components of automobiles,
airplanes, and in filters for
water purification. Much of this is due to the Graphene
Flagship, a major
European research initiative based in Sweden,
which is attempting to bring graphene to
real-world applications and is known to have
developed some 90 products. For example,
it has promoted several commercial applications,
where large technology companies
continue to experiment with graphene
to improve battery technology,
screens and even solar panels.
But, graphene still faces several
important challenges in going from being that miracle material
to reality. And the biggest problem
is its large-scale production. To
maintain its extraordinary properties,
graphene must be of almost perfect purity,
and producing it this way is expensive and difficult. Additionally,
other more affordable materials, such as silicon,
remain cheaper options
today. There are researchers who think that as
production methods improve and costs
decrease, we can expect graphene to reach
our everyday products. So, is
graphene a miracle material? Graphene is
a revolutionary material, but its potential
has not immediately transformed the world.
Scientists and companies continue to invest
in its development, hoping that one
day its practical applications will become a
reality. Maybe it's just a matter of time.
