Název v původním jazyce

Processing and properties of polyethylene/montmorillonite nanocomposites

Popis výsledku v původním jazyce

Polyethylene (PE) nanocomposite samples were prepared with 5wt% of Cloisite 25A, 30B, and 93A, and Nanofil 5 nanofillers. Two different compounding equipments were used, KO Kneader Buss and APV twin-screw extruder for sample preparation. In all samples,maleic anhydride-modified PE (PEMa) was added as a compatibilizer. The content of PEMa in mixtures was always 5wt%. The level of MMT exfoliation in the nanocomposite systems was studied by X-ray diffraction and by transmission electron microscopy observations. The properties of samples were evaluated by dynamical mechanical analysis (E* modulus at 30°C) and by the measurement of tensile properties (stress and strain at break). Because of the possibility of usage of prepared materials in packaging industry, barrier properties were measured with focus on oxygen, carbon dioxide, and water vapor permeability. The influence of two different used compounding equipments on the prepared nanocomposite samples of PE nanocomposites was discussed.
