ABSTRACT
Graphene is one of the most popular two-dimensional materials, which has attracted considerable attention all around the world. There are several principles that have been used to define graphene and graphene related nanocarbons. The first principle is to use specific names to describe the different types of graphene related materials, instead of simply using the word-graphene. The next principle is to take into consideration the lateral dimensions, which could range from tens of nanometers to micrometers and even to macroscopic dimensions. The size of lateral dimensions has an important effect when the graphene or graphene related materials are used in composites to achieve desired electrical properties, such as electrical conductivity, i.e., the percolation thresholds. Graphene materials can also be incorporated or hybridized in various ways with various other components, thus leading to additional terms, such as folded, wrinkled, activated, decorated or functionalized.
