The combination of high aspect ratio, small size, very low density, and more importantly, excellent physical properties, such as extremely high mechanical strength and stiffness, high electrical and thermal conductivity, make carbon nanotubes (CNTs) perfect candidates as ideal reinforcing fillers in high strength, lightweight polymer nanocomposites with high performance and multi-functions. In the present work, the authors have exploited these excellent physical properties of carbon nanotubes, by reinforcing linear low density polyethylene with various concentrations of multi-walled carbon nanotubes, using a cryogenic ball-milling process. The mechanical and thermal properties, as well as the morphology of the resulting nanocomposites, were characterized through tensile tests, DSC, optical microscopy, and SEM.
