Rheological and electrical properties of PE/MWCNT nanocomposites

Different nanocomposites based on LLDPE and MWCT were prepared by melt mixing in an internal mixer. The effect of nanotube content and dispersion state on the linear viscoelastic behavior and electrical conductivity of these nanocomposites were investigated. Electrical and rheological percolation threshold were determined and compared together. The electrical percolation threshold was obtained at 7.5 phr of CNT while it was found at 4.5 phr for rheological percolation threshold. The electrical conductivity was increased by 10E+11 orders of magnitude at electrical percolation threshold
