tests were performed on disk shaped specimens that were 2 mm thick
and 80 mm in diameter according to ASTM D3793[39] . An impac-tor speed of 1 m/s second was used for the tests. A minimum of five
replicates were tested for all procedures. Tukey’s multiple compar-isons tests were used to determine whether properties of different
formulations were significantly different at a 95% confidence level
[40] .
Fracture surfaces of notched impact specimens were coated in a
gold–palladium alloy and examined using a using a Zeiss EVO40
scanning electron microscope (Carl Zeiss SMT, Inc., Thornwood,
New York) to investigate morphology and adhesion of blend
components.
