摘要

Nanosized calcium carbonate (nano-CaCO_3) filled poly-L-lactide (PLLA)/polycaprolactone (PCL) biocomposites were prepared by using a twin-screw extruder. The melt flow behavior of the composites, including the entry pressure drop, melt shear flow curves and melt shear viscosity were measured through a capillary rheometer operated at a temperature range of 170-200℃and shear rates varying from 50 to 10~3 s~(-1). The melt shear flow roughly followed the power law, while the effect of temperature on the melt shear viscosity might be estimated by using the Arrhenius equation. Moreover, the relationship between the PCL weight fraction and the melt shear viscosity for the PLLA/PCLano-CaCO_3 composite was described by a quadratic equation.
