Synthesis of nanocomposite by adding graphene to polymer matrix

Nanotechnology is engineering at the atomic or molecular level and studies structures with at least one dimension between ۱ and ۱۰۰ nm [ ۱ ] . The classification of nanoparticles includes nanomaterials, fullerenes, carbon nanotubes, carbon black, nanocrystals, and nanocomposites [ ۲ ] . Nanocomposites are composite materials with one of its phases in the nanometer range. And in order to improve the properties of the resulting materials, nano-sized fillers are added to them and According to the type of matrix material, nanocomposites are generally classified into three categories: polymer, ceramic and metal [ ۳ ] .Graphene is a two-dimensional crystal composed of carbon atoms with a hexagonal lattice structure. Graphene is more suitable for nanocomposite system due to its larger specific surface area and better physical properties. Graphene has a great tendency to accumulate and clump in the polymer matrix, as a result, the uniform dispersion of graphene in the polymer matrix is the most important goal during the production of polymer/graphene nanocomposites. Good dispersion of planar nanoparticles in polymers leads to higher gas permeability properties to obtain nanocomposites. The effect of a good dispersion of nanosheets in increasing the barrierability of polymer in nanocomposites has been proven [ ۴ ] .In this research, the types of nanoparticles and then nanocomposites are described. The aim of this research is to review the synthesis of polymer nanocomposites based on graphene
