AB  - A twin-screw extruder was used to fabricate poly(butylene succinate) 
      (PBS)/high-density polyethylene (HDPE) blends (7:3 weight ratio) and blend-based 
      nanocomposites. Carbon nanotubes (CNTs), graphene nanoplatelets (GNPs), and 
      organoclays (15A and 30B) served as the nanofiller, while maleated HDPE (PEgMA) 
      acted as an efficient compatibilizer for the blend. In the composites, individual 
      nanofillers were mostly localized in HDPE domains, but some fillers were also 
      observed at PBS-HDPE interfaces. The sea-island morphology of the compatibilized 
      blend evolved into a pseudo-co-continuous morphology in the composites. 
      Differential scanning calorimetry results confirmed that PEgMA with HDPE 
      evidently accelerated the crystallization of PBS in the blend. The possible 
      nucleation effect of added fillers on PBS crystallization was obscured by the 
      formation of quasi-connected HDPE domains, causing fewer PBS nucleation sites. 
      The presence of nanofillers improved the thermal stability and burning 
      anti-dripping behavior of the parent blend. The anti-dripping efficiency of added 
      fillers followed the sequence CNT > 15A > 30B > GNP. The rigidity of the blend 
      was increased after the formation of nanocomposites. In particular, adding GNP 
      resulted in 19% and 31% increases in the Young's modulus and flexural modulus, 
      respectively. The development of a pseudo-network structure in the composites was 
      confirmed by measurement of rheological properties. The electrical resistivity of 
      the blend was reduced by more than six orders of magnitude at 3 phr CNT loading, 
      demonstrating the achievement of double percolation morphology.
