A Review on Effect of Clay Nanoparticles on the Stable and Dynamics Rheological Properties of Polymeric Nanocomposites

Polymeric nanocomposites are one of the most diverse today’s materials and have unique properties, but a polymer alone is not capable of exhibiting a wide range of desirable rheological properties. Therefore, for development and high efficiency of these nanocomposites, the need to merge these composites with materials such as clay nanoparticles that is one of the most commercial and effective nanoparticles. So, in this study, a review on previous researches has been performed to investigate the effect of clay nanoparticles on polypropylene/clay nanocomposite rheological properties of immiscible polymeric mixtures. Based on the studies, it was found that for the poor interactions of polymer/clay nanoparticles composites and in systems where the dispersion of nanoparticles was less stable, the addition of layer silicates had minimal effect on the rheological behavior of the nanocomposites. For the strong interactions of polymer/clay composites, a transition from rheological behavior of liquid species to solid species behavior is observed at relatively low amounts of silicate (1–2 wt.%). Studies show that clay nanoparticles contribute to the development of fuzzy morphology by increasing the viscosity and elasticity of the polymer matrix.
