AB - Conductive polymer composites (CPCs) consist of a polymeric matrix and a conductive filler,for example, carbon black, carbon fibers, graphite or carbon nanotubes (CNTs). The criticalamount of the electrically conductive filler necessary to build up a continuous conductivenetwork, and accordingly, to make the material conductive; is referred to as the percolationthreshold. From technical and economical viewpoints, it is desirable to decrease the conductive-filler percolation-threshold as much as possible. In this study, we investigated the effectof polymer/conductive-filler interactions, as well as the processing and morphological developmentof low-percolation-threshold (Φc) conductive-polymer composites. The aim of thestudy was to produce conductive composites containing less multi-walled CNTs (MWCNTs)than required for pure polypropylene (PP) through two approaches: one using various mixingmethods and the other using immiscible polymer blends. Variants of the conductive PPcomposite filled with MWCNT was prepared by dry mixing, melt mixing, mechanofusion,and compression molding. The percolation threshold (Φc) of the MWCNT-PP compositeswas most successfully lowered using the mechanofusion process than with any other mixingmethod (2-5 wt%). The mechanofusion process was found to enhance formation of a percolationnetwork structure, and to ensure a more uniform state of dispersion in the CPCs. Theimmiscible-polymer blends were prepared by melt mixing (internal mixer) poly(vinylidenefluoride) (PVDF, PP/PVDF, volume ratio 1:1) filled with MWCNT.
