**1. Introduction to graphene/polymer nanocomposites**

Graphene, as well as its, distinguish variants, possess excellent characteristics. A remarkable achievement for them, because of these traits is their utility as fillers in

the fabrication of composites. There are various factors that impart critically in the properties of graphene-polymer composites. They include dispersity of fillers, bonding between matrix and filler, the ratio of graphene filler to the polymer matrix, and quality. However, there are several fabrication approaches for undergoing modification in these factors in order to acquire desirable properties. In general, graphene comprises a very high aspect ratio, therefore it is capable of doing several modifications in properties of composites even at a very low percolation limit.
