Abstract: In the current study the dependency of morphology and thermal
behavior of medium density polyethylene (MDPE) powder
reinforced with 0, 5, 10 and 15 wt.% nano-sized Al2O3 particles
on mechanical milling were studied. The effects of milling
time on the morphology and the thermal behavior were investigated
by Transition Electron Microscopy (TEM), Scanning
Electron Microscopy (SEM), Differential Scanning Calorimetery
(DSC) and Thermo Gravimetric Analyzer (TGA). The
TEM micrographs obtained from the nanocomposites proved
that mechanical milling could be an adequate method to disperse
nano-sized hard particles throughout the polymer. The
SEM micrographs of pure MDPE showed that regular shape
powder converted to the flake shapes as milling time increased.
Also the results illustrated that an increase in milling time
caused to decrease the agglomeration of alumina. The DSC
profiles of samples elucidated that ball milling had little effect
on crystalline temperature and melting point of all materials
including MDPE and its nanocomposites. The nanocomposite
exhibited more thermal stability than pure polyethylene proved
by TGA tests.
