Medium-density polyethylene, carbon nanotube

Pulikkathara M X, Kuznetsov O V, Peralta I R G, Wei X, Khabashesku V N (2009) Medium density polyethylene composites with functionalized carbon nanotubes, Nanotechnology 20 195602. 

Noroozu and Zeboria [57] have measured the effect of multiwalled carbon nanotubes on the mechanical and thermal properties of medium-density polyethylene matrix carbon nanotube nanocomposites. 

The milling process can be a suitable method for producing medium-density polyethylene-multiwalled carbon nanotubes. 

Addition of carbon nanotubes to medium-density polyethylene causes a change in its morphology at constant milling parameters. 

Figures 3.1 and 3.2 show electron micrographs of medium-density polyethylene before milling and a transmission electron micrograph of carbon nanotubes, respectively.

FIGURE 3.3 Scanning electron micrograph of (a) medium-density polyethylene, (b) medium-density polyethylene containing 0.5% of carbon nanotubes, and (c) medium-density polyethylene containing 1% of carbon nanotubes. 

Cold welding of medium-density polyethylene nanocomposites is much more extensive than that of neat medium-density polyethylene. This difference is attributed to the increased thermal conductivity of neat medium-density polyethylene when carbon nanotubes are added to the formulation.
