Irish Scientists Find Cheaper Way of Producing High Quality Graphene
Groundbreaking research by scientists from Trinity College Dublin in Ireland has led to development of simple recipe that allows mass production of wonder material graphene. Generally, graphene is difficult to produce and the current best techniques in labs results in formation of less than half a gram per hour.
But, now researchers have found a way to mass-produce pure graphene in the kitchen by making use of soap and a blender. They put graphite powder and a solvent fluid in a laboratory mixer for spinning. It was later analyzed with an electron microscope.
Their experiment resulted in formation of graphene at a rate of about 5 grams per hour. Later on, they used different types of motors and solvents to confirm accuracy and scalability of the process. Jonathan Coleman, from Trinity College Dublin, Ireland, said despite the simple process can be performed at home; people are highly advised not to follow it.
Coleman said the properties of graphite powder equally alters amount of dishwashing liquid required develop graphene. Researchers advise that the novel technique will work more appropriately at industrial levels where it can produce 100 grams per hour from 10,000 liter vat with the right motor.
Main drawback of using the experiment is that it does not convert all the graphite to graphene and one must have to separate two materials afterwards. But, Coleman said that despite of its drawback, the novel experiment is quite encouraging.
