Abstract
Toe mechanical properties ofpolypropylene (PP)-calcium carbonate (CaCO3) nanocomposites were studied in this work. In this study stearic acid was used as a new interface modifier during the compounding of the nanocomposites with a twin screw extruder. The concentration in weight of the nanofiller in the compounds was of 1.5%, 2.5% and 5.0% respectively. Toe nanocomposites were characterized by impact resistance and tensile tests. Toe interaction between CaCOJ and stearic acid was analyzed by FTIR. Toe infrared spectra <lid not show any chemical reaction between CaCOJ and stearic acid. Toe elongation at break and impact resistance were increased in nanocomposites with interface modifier ( stearic acid in hopper ofthe extruder).
