Graphene, an allotrope of carbon, is also the basic structural element of several other allotropes such as charcoal, graphite, fullerenes and carbon nanotubes. This material finds application in high-performance markets such as electronics, medical and military among others, and could re-define the nanocomposites market in the future. Graphene nanocomposites have shown a great growth potential in certain industry segments such as electronics, aerospace, green energy and automotive. Over the past few years, technology has advanced significantly and the synthesis of graphene in bulk amount became possible. This is a milestone in the development of graphene based composite and hybrid materials.
