The development of layer multiplying technique using coextrusion is able to create polymer films having several thousand layers with individual layer thickness ranging from a few microns to several nanometers. The number of individual layers in the films is controlled by the number of layer multiplying elements (LMEs) added to the system. The main focus of our research is to investigate the effects of polymer based nanocomposites combinations, layer quantity, processing files and flow path design on the morphology, bulk properties and layer stability of the coextruded films. In this research work, CNTs filled PS and TPV blends with different number of layers were compounded using Coextrusion technique. The effect of number of layers on the localization of CNTs in the polymer blends was evaluated. Further nanocomposites were also characterized for their mechanical properties.
