Maleic-anhydride grafted ethylene-propylene diene monomer (EPDM-g-MA) toughened polyamide6 (PA6) nanocomposites containing carbon nanotubes (CNT) were prepared using laboratory internal mixer at 230°C. Effect of different blend composition ratios on the mechanical and structural properties of the nanocomposites was investigated. Results showed that upon the addition of CNT, a significant improvement is observed in the impact strength and elongation at break retaining the tensile modulus to a sufficiently high value. Microstructural observation of the sample fracture surfaces revealed a toughened microstructure.
