To this aim, four studies were carried out; two involving the ‘top-down’ synthesis of graphene from graphite and two involving the ‘bottom-up’ synthesis of graphene from molecular precursors.

In the first study a series of intermediate materials between graphene oxide (GO) and reduced GO (r GO) were successfully produced using a well-controlled reduction reaction, and the trend in their properties was explored, while in the second study r GO was successfully produced using a novel method that is simple, scalable and environmentally friendly.
