In order to make a more efficient network formation of CNTs in polymer matrix, ethylene/1-octene copolymers/carbon nanotubes (EOCs/CNTs) and polypropylene/carbon nanotubes (PP/CNTs) nanocomposites were fabricated by coating CNTs on the surface of polymer pellet, and after hot pressing CNTs between the polymer pellets would connect together and easily form network structure in the polymer matrix. In this project, CNTs have successfully served as nanofillers for obtaining highly electrical conductive polymer nanocomposites (PNCs). The effects of nanofiller loading levels and the processed temperature on the rheological behaviors, crystal structure, electrical conductivity, optical properties and dielectric properties were systematically studied for both series of samples. The EOCs/CNTs PNCs processed at 100 °C with 6.8 wt% CNTs present the highest σ of 0.015 S/cm. However, the PP/CNTs PNCs with 2.0 wt % CNTs and prepared at 120 °C exhibit the highest conductivity of 0.16 S/cm.
