AB  - In this study, effects of two different types of porous alumina nanoparticles 
      have been incorporated into high-density polyethylene (HDPE) to study their 
      impact on the properties of the HDPE composite. The dispersion of fillers in the 
      HDPE matrix was evaluated by scanning electron microscopy (SEM). Differential 
      scanning calorimetry (DSC) and thermogravimetric analyzer (TGA) integrated with 
      Fourier transform infrared spectroscopy (FTIR) were applied to investigate the 
      calorimetric behavior and thermal stability and to analyze the polymer 
      decomposition, respectively. The dielectric properties were determined by a 
      broadband dielectric spectroscopy. The effect of filler loading on the tensile 
      properties and melt flow index was also examined. A homogenous distribution of 
      the fillers was observed at low loading of alumina particles (below 5 wt. %). 
      However, agglomerates of sub-micro size were formed extensively on samples with 
      high loading of fillers (above 7 wt. %). A significant improvement of the 
      thermo-oxidation stability of the composite was observed. The permittivity values 
      of the prepared composites also increased with the addition of the fillers. The 
      incorporation of fillers also increased the electrical conductivity values of the 
      prepared composites at high frequencies.
