In this work low density polyethylene (LDPE, Riblene FL34 Polimeri Europa)/organoclay (Dellite 72T, Laviosa) nanocomposites were prepared via direct melt intercalation in a co-rotating twin screw extruder. The objective was to investigate the effects of feed and processing conditions upon the formation and properties of LDPE nanocomposites. The nanocomposites morphology was investigated by X-ray diffraction (XRD) and by transmission electron microscopy (TEM) analysis. The processability of nanocomposites was investigated via melt rheology. The incorporation of the organoclay in LDPE improved thermal stability, barrier properties and don't significantly impair the LDPE processability.

Abstract

In this work low density polyethylene (LDPE, Riblene FL34 Polimeri Europa)/organoclay (Dellite 72T, Laviosa) nanocomposites were prepared via direct melt intercalation in a co-rotating twin screw extruder. The objective was to investigate the effects of feed and processing conditions upon the formation and properties of LDPE nanocomposites. The nanocomposites morphology was investigated by X-ray diffraction (XRD) and by transmission electron microscopy (TEM) analysis. The processability of nanocomposites was investigated via melt rheology. The incorporation of the organoclay in LDPE improved thermal stability, barrier properties and don't significantly impair the LDPE processability.
