    The conducting polymers and polymeric composites have attracted considerable attention in recent years because of their breadth applications in advanced technologies, for example, in antistatic coatings, electromagnetic shielding. For all applications, elastomers are reinforced with fillers to promote their performance by incorporating materials such as silica, clay, carbon blacks, etc. Graphite is a layered material with high aspect ratio in its exfoliated state; it is also considered as one of the strongest materials per unit weight and has unique functional properties such as good electrical and thermal conductivities, and good lubricating properties. In other side graphene have recently received significant attention due to its outstanding electronic, mechanical and thermal properties. NBR-based Nano composite was prepared and mechanical and functional properties were studied. The dispersion of the filler in the polymer matrix was studied using the Transmitted light metrological microscope. Methodology Two different experimental trials (Preparation of NBR/Graphite composite and NBR/Graphene Nano composite) with different treatments (Phr levels) were conducted during this study. Nitrile rubber composites were prepared accordance with Brabender Plasticorder (Model: PL-2000; 26 manufacturers: ArtisanTM Technology Group).
