Abstract
Nanocomposites of linear low-density polyethylene (LLDPE), with three different amounts of polyhedral oligomeric silsesquioxanes (POSS), were prepared through melt-mixing in a batch-mixer at 150 °C. The structure of the prepared nanocomposites was studied by X-ray scattering and optical microscopy. The surface morphology of the nanocomposites was investigated through field-emission SEM. The thermal properties of the pure LLDPE and nanocomposites were studied by differential scanning calorimeter (DSC). Thermomechanical properties were assessed on a Paar-Physics MCR501 rheometer using a solidstate rectangular fixture. Results exhibited a significant improvement in both the storage and loss moduli of the neat LLDPE upon the incorporation of the POSS particles. A substantial improvement in thermal stability was also observed in the high-temperature region.
