Abstract :
It has been reported that the production of defect
free graphene is possible by the application of a kitchen
mixer. Yet, we note that the natural-surfactant role in the
exfoliation mechanism by a kitchen mixer has rarely been
discussed. To investigate the possibility of graphene
exfoliation in a bio-surfactant medium, we have produced
graphene from the co-mixing of graphite and gum Arabic.
Through the modelling of bulky graphite as a single
composite disc, we have shown that the exfoliation of
graphite crystal may be possible through rotational motion
of graphite surface. In this paper, we also have developed
two simple metric systems that were designed from the
application of UV spectroscopy for in situ measurement of
graphene sheet size after exfoliation step.
