Abstract: 

Nanocomposites based on polyamide 6/polypropylene (PA6/PP 67/33) blend containing 2.5 to 10phr of nano-CaCO3, and 5phr of maleated polypropylene (PP-g-MAH) as compatibilizer were prepared by melt compounding followed by injection molding. The mechanical properties, water absorption, as well as shrinkage behavior were characterized and the morphology was studied using scanning electron microscopy. The presence of PP, PP-g-MAH and nano-CaCO3 lowered the amount of water absorption as high as 72 wt%. Morphology analysis indicated that the addition of PP-g-MAH can significantly improve the adhesion between PA6 and PP phases. The incorporation of PP-g-MAH led to 24% increase in flexural and impact strength, 27% rise in tensile strength and approximately 100% increase in elongation-at-break. The addition of nano-CaCO3, particles increased the impact resistance and flexural strength. The results of experiments indicated that the maximum flexural strength was achieved by adding 5phr of nano-CaCO3, which was 16% greater than pure PA6, and the maximum impact strength was attained by adding 7.5phr of nano-CaCO3, which was 29% superior compared to pure PA6. The incorporation of 10phr ofnano-CaC03 particles led to filler agglomeration and, consequently, the impact strength was dramatically dropped. Dimensional characterization of molded samples revealed that the incorporation of PP-g-MAH can raise the shrinkage', but the addition of nano-CaC03 has not had any considerable effect on the shrinkage of nanocomposites.
