Suspension models in HDPE/clay nanocomposites

Nanocomposites have attracted attention in recent years because their mechanical, physical, optical, and rheological properties can often be modified with a minimal increase indensity as a result of low inorganic loading [1]. A direct consequence of the incorporation of nanofillers in a moltenpolymer is a significant change in the viscoelastic properties. Consequently, linear rheology is a way generally used to assess the state of dispersion of nanocomposites directly in themolten state. Dynamic melt rheometry is a powerful means to inspect the effect of inorganic filler on the motion andrelaxation of polymer chains [2]. The study aims to improve the knowledge about the relation between rheological behavior and the structure of polymer/clay nanocomposites using several proposed models for rheology of suspensions [3
