which clearly shows the variation of
the samples color by increasing the TiO2
nanofiller.
At the final stage, nanocomposite films with a
thickness of about 60±5µm were obtained by
blowing into the molten nanocomposite with
Clextral E20T equipment with blow up ratio of 2.
Tensile testing of the film samples was carried out
in the machine direction (MD) according to ASTM
Standard D882-02 on an Instron 1130 equipped
with a 200lb load cell. The gauge length of the test
samples was 50.8mm, and the width of the samples
was 13.8mm. The crosshead speed of the test was
maintained at 50mm/min during the duration of
each test. Ten samples of each film were tested &
averages were reported.
