Abstract [en]

In this work, organoclay reinforced high density polyethylene (HDPE) nanocomposites were prepared at lab scale using a batch mixer. Processing conditions, maleic anhydride modified polyethylene (MAPE) type and MAPE/clay weight ratio, were optimized. The microstructure of the resultant nanocomposites was analysed by XRD and melt rheology tests and flexural properties and thermal stability were evaluated. Three types of MAPEs with different melt flow index (MFI) and MA content all improved interaction between HDPE and clay, and promoted clay dispersion. Nanocomposites where the MAPE with MFI most similar to HDPE was used showed the best exfoliation of clay and strongest HDPE-clay interface. Mechanical properties were slightly improved while thermal stability was distinctly enhanced in these HDPE nanocomposites compared to neat HDPE and HDPE nanocomposite without MAPE. The prepared HDPE nanocomposites show potential to improve thermal stability of wood plastic composites for structural applications providing.
