Sensors

Graphene sensorsGraphene is an ideal material for sensors. Every atom in graphene is exposed to its environment allowing it to sense changes in its surroundings.

DefenceThe extreme sensitivity of graphene-based sensors could also be tuned to chemical warfare agents and explosives. This could allow for early warning detection systems for soldiers in the field potentially saving lives.

The high structural strength of graphene makes it an ideal material to use for manufacturing of composite materials like aircrafts, body armor, vehicles etc.

Roll to Roll Method

This method was developed in 2011 by Prof. Shou-En Zhou. He devised a whole new method for production of Graphene using materials like Argon, Methane a Copper plate and a furnace which can reach temperatures of 1000˚C. This method has overcome three of the most pressing issues regarding the commercialization of Graphene, Cost; Scalability; and Production time.

ADVANTAGES

•Low cost•Less Production Time•High Quality•High Scalability
