摘要：

xGnP-Reinforced LLDPE nanocomposites have been prepared using co-, counter- and modified co-rotating screw systems. The highest tensile strength and modulus were shown in the case of composites made by counter-rotating screws. The percolation threshold of exfoliated graphite nanoplatelet/LLDPE nanocomposites was between 12 and 15 wt.-%. The change of crystallinity caused by exfoliated graphite nanoplatelet loading was monitored using DSC and XRD. It was found that solution mixing showed better dispersion of exfoliated graphite nanoplatelets than melt mixing, and counter-rotating screws produced better dispersion of the exfoliated graphite nanoplatelets than co- and modified co-rotating screws even though bubbling appeared during mixing in the barrel.
