GRAPHENE AND ITS FUTURE
• What is Graphene?
• Graphite Discovery.
• Future Scope.
The wonder Material of
the 21st Century.
What Is Graphene?
• Single layer of Graphite.
• Honey comb lattice made
• Graphene is among several allotropes (forms)
Forms of carbon:
a) Graphite 3D
b) Diamond 3D
d) Carbon nanotube 1D
e) Graphene 2D
16th Century: Graphite Ore(England in 1564)
17th Century: Cannon and musket balls 18th Century: Pencil Industry
Graphene- the mother of all graphites
‘Graphene’ was first isolated in the lab by Professor Andre Geim with former student
Konstantin Novoselov at the University of Manchester, England in 2004
Sir Andre K. Geim, FRS Sir “Kostya” Novoselov, FRS
2010 Nobel Prize
Properties of Graphene
• Thinness material.
• Electrically Conductive.
• Flexible & Stretchable.
• Transparent. Thinnest Light Bulb Lighter, stronger, thinner wheels
• Most reactive form of carbon.
• Burns at very low temperature.
• Harder than diamond and steel etc. Bulletproof Jackets
“It would take an elephant, balanced on a pencil to break through a sheet of graphene the
thickness of cling film.”
Applications of Graphene
• Electrical engineering
• Mechanical engineering
• Electronics Engineering
• Biomedical Engineering
• Solar cells
• Water Filters
Advancements in touch screens.
Hand holding transparent future tablet.
In the future, satellites, airplanes, and cars could be manufactured out of the new composite materials.
In future the mobile technology would be completely dependent on the graphene.
The phones would be connected on the laptop and computer without any device & then the
work can be done on the laptop.
• Graphene is single layer of carbon atoms.
• Discovered in 2004
• Exceptional mechanical and electrical properties.
• Strongest known material among all materials.
• Graphene has applications in every sphere of life like
touch screens, solar cells, water filters etc.
