INTRODUCTION Composites are widely used in various fields such as transportation, construction, electronics and consumer products. It offers combinations of rigidity, strength and weight that are difficult to achieve separately from individual components. [1] In brief, composites are generally 2 or more closely interacting materials which have different physical and chemical properties in intimate contact with each other. Polymer science uses the concept of a composite as a material formed by combining different phases. In composite materials, one phase is usually continuous called the matrix; while the other phase is a reinforcing material called the dispersed phase. Figure 1. General shape of composite (https://goo. gl/images/29fRHQ) Nanocomposites on the other hand is a relatively new class of materials with handheld, ultra-thin phase sizes, typically at a few nanometers level.[2] In nanotechnology, polymer nanocomposites (PNC) have attracted academic and industrial interest due to exceptional electrical, mechanical and permeability properties. [3] Because of the nanometer size features of nanocomposites, they typically have unique properties that are not shared by more conventional microcomposite replacements, for this reason, it offers new technology and business opportunities.

[10] Polymer nanocomposites, particularly polymer layered silicate (PLS) nanocomposites, are an alternative to conventional (macroscopically) filled polymers. Depending on nanometer size distributions, nanocomposites significantly improved properties when compared to conventional composites. [11] ‘’ For example, the mechanical properties of a Nylon-6-layered-silicate nanocomposite, with a silicate mass fraction of only 5%, show excellent improvement over those for pure Nylon-6. ‘’
