Abstract
The effects of compatibiliser molecular weight, temperature of the first mixing zone of the extruder and nanoclay loading on the mechanical and thermal properties of polymer–clay nanocomposites (PCNs) were investigated. It was found that the molecular weight of the compatibiliser, the temperature of the first mixing zone of the extruder and the nanoclay content have significant effects on the mechanical and thermal properties of the polyethylene–clay nanocomposites. The blending of the high and low molecular weight compatibilisers allowed a more efficient interface between the nanoclay and the polymer matrix. Coupling a more efficient bonding with the high shear in the first mixing zone of the extruder at a low temperature produced an intercalated/exfoliated nanoclay filler resulting in enhanced mechanical properties of the PCNs.
