ABSTRACT
Polymer blends can be narrated as the bodily aggregate of two or greater polymers. Polypropylene (PP) is considered as one of the topmost assuring substitutes for engineering substances due to its splendid processability, rigidity, thermal stability, resistance to oil, recyclability and relatively low cost. This chapter specialises in the effect of different ratio of nanosilica particles on the mechanical properties of 50PP/50 styrene–ethylene butylene–styrene (SEBS) blend. Nanocomposites based on PP/SEBS/nanosilica were prepared by melt mixing. Different concentrations of nanosilica were used as fillers in this study in order to explore their influences on mechanical properties and contribute to the enhancement of already existent results by correlating mechanical-dynamic mechanical and morphological properties. Significant improvement in the mechanical properties of the P50/SEBS50 blend has been observed by the incorporation of nanosilica. Tensile stress value of P50/SEBS50 blend containing 10 wt% of nanosilica is approximately 35% higher than the tensile stress value of P50/SEBS50 blend.
