High density polyethylene (HDPE)/multi-walled carbon nanotube (MWCNT) nanocomposites were prepared by melt mixing using twin-screw extrusion. The extruded pellets were compression moulded at 200 ( for 5min followed by cooling at different cooling rates (20 (/min and 300 (/min respectively) to produce sheets for characterization.
