Abstract

We investigate the effect of small amounts of organoclay on th e crystallinity and dynamic-mechanical properties of bio-based blends of poly(lactic acid) (PLA) and polyamide 11 (PA11). Virgin and filled blends were prepared by melt compounding the constituents using a twin-screw extruder. Wettability considerations suggest that the filler unevenly distribute inside the material. This affects both the crystallinity of each phase and the blend microstructure. Controlling such phenomena can lead to higly "engineerized" materials with tailored properties. In particular, the typically poor mechanical performances of bio-based polymers can be overcame owing to the synergism among reinforcing action of the filler, its possible compatibilizing action and its impact on the crystallinity of the hosting phase.
