AB  - In this study, a graphene nanoplatelet (GNP) was used as a reinforcing filler to 
      prepare poly(vinylidene fluoride) (PVDF)/high density polyethylene (HDPE) 
      blend-based nanocomposites through a melt mixing method. Scanning electron 
      microscopy confirmed that the GNP was mainly distributed within the PVDF matrix 
      phase. X-ray diffraction analysis showed that PVDF and HDPE retained their 
      crystal structure in the blend and composites. Thermogravimetric analysis showed 
      that the addition of GNP enhanced the thermal stability of the blend, which was 
      more evident in a nitrogen environment than in an air environment. Differential 
      scanning calorimetry results showed that GNP facilitated the nucleation of PVDF 
      and HDPE in the composites upon crystallization. The activation energy for 
      non-isothermal crystallization of PVDF increased with increasing GNP loading in 
      the composites. The Avrami n values ranged from 1.9(-)3.8 for isothermal 
      crystallization of PVDF in different samples. The Young's and flexural moduli of 
      the blend improved by more than 20% at 2 phr GNP loading in the composites. The 
      measured rheological properties confirmed the formation of a pseudo-network 
      structure of GNP-PVDF in the composites. The electrical resistivity of the blend 
      reduced by three orders at a 3-phr GNP loading. The PVDF/HDPE blend and 
      composites showed interesting application prospects for electromechanical devices 
      and capacitors.
