Abstract

High-density polyethylene (HDPE)/poly(ethylene terephthalate) (PET) (90/10 wt%) blends and HDPE/PET/multi-walled carbon nanotubes (MWCNTs) nanocomposites were prepared by melt mixing process, and the influence of MWCNTs on the mechanical and rheological properties of the nanocomposites were investigated. MWCNTs were added up to 5 wt% in the HDPE/PET matrix. Transmission electron microscopy (TEM) images revealed that the MWCNTs were homogeneously dispersed in the HDPE/PET matrix. Improvement of mechanical properties was observed by the addition of MWCNTs compared with HDPE/PET blends. Prominent increases in the complex viscosity and storage modulus of the nanocomposites were found with increasing MWCNT content.
