Morphology and Mechanical Properties of Natural Rubber-PCL Core-Shell/PLA Composites

Abstract:

Natural rubber (NR)/Polycaprolactone (PCL) core-shell (NR-ad-PCL), from admicellar polymerization, was as an impact modifier for the composites. PLA was mixed with NR-ad-PCL with different NR-ad-PCL contents at 5, 10, 15 and 20 wt%. PLA-based composites were prepared by co-rotating twin screw extruder. The morphology of the composites was observed by Field emission scanning electron microscope (FE-SEM). Mechanical properties of the composites were investigated by dynamic mechanical analyzer and pendulum impact tester. The impact strength of the PLA filled with NR-ad-PCL increased while modulus of the PLA composites decreased with increasing rubber contents.
