GRAPHENE A RAY OF HOPE
Author: Akanksha Kashyap
The word ‘graphene’ has significantly become synonymous to ‘miracle material’ as, in today’s advancing technology era this carbon composite material can be used in any of the field whether it is medical , defence , commercial use or in aerospace field . It is a 2D one atom thick nano-material which has some very unique properties such as it has tremendous tensile strength i.e. 130 GPa and extraordinary specific penetration energy which is nearly 10 times higher than normal steel .Graphene as a carbon composite material is unique because of its sp2 hybridization structure & it’s extremely thin atomic thickness which is 0.345 nm.These properties make it a remarkably strong i.e. nearly 200 times stronger than steel as well as an excellent conductor of heat and electricity. The carbon-carbon bonds in graphene are so small in length and so strong that they prevent thermal fluctuations from destabilizing it. In addition to that, the material is extremely diverse and can be combined with other elements including gases and metals to produce different composite materials consisting range of superior properties. Graphene being a carbon composite material is also lightweight and stiff in nature thus making it a potential material to replace the aramid fibre based polymer composites used in armour systems in current scenario. The aim of this research is to study the behaviour of graphene under various extreme conditions so that it could potentially be used in the battle field as body armours or in our defence system .This study will discuss the potential of graphene based non-materials with regard to penetration energy, ballistic performance, flame resistance, electromagnetic interference shielding, electrostatic-charge dissipation, sensors, corrosion protection. The gestalt of defence applications of polymer/graphene based nano-material may offer future perspective to develop promising materials which will contribute in the growth of our country’s defence system.
