. Synthesizing procedure
The TiO2
/LDPE samples were prepared by melt
compounding of the nanoparticles and the polymer
using a DO-CORDER C3 twin screw extruder (L/D
=36). The screw speed (which was increased before
increasing feed flow rate and entering the feed into
the hopper) was set to 60rpm proportionate to feed
flow rate and the thermal zones of 150, 160, 170
and 180o
C respectively from the feed inlet. Finally,
the samples were pelletized by granulator. As the
feed flow rate increases - when molten polymer
