The accurate determination of nanoparticle localization in immiscible polymer blends with co-continuous morphology by rheological technique has always been a difficult job. In this study we showed how the relaxation time spectrum (H(λ)) of polymer blends can be employed to determine the localization of MWCNTs in PC/PVDF Polymer blends with co-continuous morphology. This was carried off by comparing the H(λ) of MWCNTs filled blend samples with the filled and unfilled polymer component. It was demonstrated that MWCNTs is preferentially localized in PC phase which was confirm by TEM micrograph.
