Abstract

A comparative study of unary and binary carbon nanofiller reinforced high density polyethylene (HDPE) composites with 4 wt.% nanofillers was carried out in order to assess the reinforcement effect and synergy of carbon nanofillers with different dimensions. Rheology and resistivity tests indicate that the relative effectiveness of generating rheological and conductive networks is as follows: multi-walled carbon nanotubes (MWCNTs) > carbon black (CB) > graphene nanoplatelets (GNPs), while the reinforcement effect in modulus is: GNPs > MWCNTs > CB, at the same loading. The resistivity of all the HDPE/CB/MWCNT composites is quite close to the that of HDPE/MWCNT composites, indicating CB may be a good replacement for MWCNTs considering the relatively low cost of CB. A synergistic effect in modulus is observed in the HDPE/GNP/ MWCNT and HDPE/CB/MWCNT composites due to the formation of nanofiller-polymer-nanofiller network structures.
