The tensile properties were measured using a Zwick Z100 tensile tester at a crosshead speed of 10 mm/min. The dimensions of the dumbbell-shaped tensile bars were 12 mm in length of narrow parallel-sided portion, 0.8 mm in thickness and 2 mm in width. The notched Izod impact toughness was tested using an impact analyzer (Zwick 5102, Germany) according to ASTM D256. The flexural properties were measured according to ASTM D790. The
dimensions of the specimen for impact and flexural measurements were 63.5 12.7 3.6 mm3. All the tests were performed at ambient temperature.
