TI  - Size effects of graphene nanoplatelets on the properties of high-density 
      polyethylene nanocomposites: morphological, thermal, electrical, and mechanical 
      characterization.

AB  - High-density polyethylene (HDPE)-based nanocomposites incorporating three 
      different types of graphene nanoplatelets (GnPs) were fabricated to investigate 
      the size effects of GnPs in terms of both lateral size and thickness on the 
      morphological, thermal, electrical, and mechanical properties. The results show 
      that the inclusion of GnPs enhance the thermal, electrical, and mechanical 
      properties of HDPE-based nanocomposites regardless of GnP size. Nevertheless, the 
      most significant enhancement of the thermal and electrical conductivities and the 
      lowest electrical percolation threshold were achieved with GnPs of a larger 
      lateral size. This could have been attributed to the fact that the GnPs of larger 
      lateral size exhibited a better dispersion in HDPE and formed conductive pathways 
      easily observable in scanning electron microscope (SEM) images. Our results show 
      that the lateral size of GnPs was a more regulating factor for the 
      above-mentioned nanocomposite properties compared to their thickness. For a given 
      lateral size, thinner GnPs showed significantly higher electrical conductivity 
      and a lower percolation threshold than thicker ones. On the other hand, in terms 
      of thermal conductivity, a remarkable amount of enhancement was observed only 
      above a certain filler concentration. The results demonstrate that GnPs with 
      smaller lateral size and larger thickness lead to lower enhancement of the 
      samples' mechanical properties due to poorer dispersion compared to the others. 
      In addition, the size of the GnPs had no considerable effect on the melting and 
      crystallization properties of the HDPE/GnP nanocomposites.
