A Less Expensive Method to Make Graphene?

From BBC News:
Graphene is thin, strong, flexible and electrically conductive, and has the potential to transform electronics as well as other technologies. 
An Irish-UK team poured graphite powder (used in pencil leads) into a blender, then added water and dishwashing liquid, mixing at high speed. 
The results are reported in the journal Nature Materials. 
Because of its potential uses in industry, a number of researchers have been searching for ways to make defect-free graphene in large amounts. 
The material comprises a one-atom-thick sheet of carbon atoms arranged in a honeycomb structure. Graphite - mixed with clay to produce the lead in pencils - is effectively made up of many layers of graphene stacked on top of one another. 
Jonathan Coleman from Trinity College Dublin and colleagues tested out a variety of laboratory mixers as well as kitchen blenders as potential tools for manufacturing the wonder material.
