Analysis of properties of polymer nanocomposites on the basis of nature of interphase property variation

The effect of adding a nano inclusion (Alumina) to polymer matrix (polypropylene) has been analyzed after making a numerical model. On addition, interphase formation in between the inclusion and the polymer matrix occurs. The properties vary in this layered interphase. A solid model of the Representative Volume Element (RVE) of polymer nanocomposite was prepared and calculations were done based on types of variations and these properties were entered into the solid model and mesh model was prepared. On imposing various boundary conditions and taking displacement under small strain case, solutions were done. On comparing these obtained results with the reference values, huge improvement in the mechanical properties like Young Modulus and Poisson ratio was observed.
