“…Nanoparticles have not only the ability of improving the final performance of the blend, but also the capability of enhancing the compatibility between the constituents [1][2][3][4][5][6][7][8][9] . In this way, the literature on polymer blend nanocomposites reveals that the performance of the nanoparticles is strongly depended on their localization and their state of dispersion in the polymer blend systems [5,6,[10][11][12][13] .…”

Correlation of rheological response with microstructure and also the tensile mechanical properties of Nanoclay-filled Polyethylene (PE)/Ethylene vinyl acetate (EVA) blends were studied. From transmission electron microscopy observations, the same clay localization within PE-and EVA-rich blends was revealed. But the better clay dispersion in the EVA-rich blend was found by analyzing the changes in the linear viscoelastic rheological properties discussed by the fractional Zener model and the power law expression. Clay influences on the tensile properties of PE-and EVA-rich blends were in good agreement with its microstructure, implied by the rheological studies.

“…Entezam et al [109] analyzed the influence of nanoclay localization within immiscible PP/PET 90/10 and 10/90 blends containing 0, 1, and 5 wt% of an organoclay on mechanical properties of the blends. They found that the organoclay localized at the interface of the blends had no compatibilization effect on the interfacial adhesion reinforcement.…”

“…Recent reports revealed remarkable enhancements in polymer properties by the dispersion of various nanometer inorganic fillers [19,20]. Imidazolium based ionic liquids have been evaluated as clay modifiers and the major advantages are the enhancement of the thermal and flame retardant characteristics of the clays, in comparison to ammonium modified clay [21][22][23].…”

Polypropylene montmorillonite (MMT) nanocomposites were prepared by melt blending using two different organoclays modified with imidazolium and alkylammonium surfactants. The imidazolium and ammonium modified organoclays were characterized by the FTIR and SEM analysis. The effect of organic clay (MMT) on the physical properties of polypropylene was evaluated, thermal and rheological properties with different filler weight percentage. Differential scanning calorimetric results showed that imidazolium modified clay (IMMT) exhibits low melting temperature compared to the ammonium modified clay (AMMT). The crystallinity analysis showed that crystallization improved in all nanocomposites irrespective of surface modification; the thermogravimetric analysis showed that the imidazolium modified polymer composites are more thermally stable than conventional ammonium modified composites. The Transmission Electron Microscopy (TEM) analyses indicated that the PP-IMMT composites displayed exfoliated morphologies compared with the intercalated structure in PP-AMMT, and the rheological analysis at 180 ∘ C showed an enhancement in the viscoelastic properties as the clay concentration increases. The melt viscosity, crossover modulus, and relaxation times were comparable for both the surface modified composites with two different cations. The imidazolium based surfactant was found to be an effective organic modification for MMT to prepare thermally stable PP/MMT nanocomposites.
