Abstract

Nanocomposites based on biodegradable poly(ε-caprolactone) (PCL) and attapulgite (AT) were prepared by solution blend. The morphology and rheological behaviors of the blends were examined. SEM observation showed that AT nano-rods were well dispersed in the PCL matrix in a nanometer scale at low AT content and a severe aggregation would happen at high AT content. The rheological behaviors of the polymer/fibrous clay nanocomposite samples were investigated by an Advanced Rheometric Expansion System with parallel plate geometry. The effects of AT content on the viscoelastic behaviors of the PCL/AT nanocomposites were also confirmed by rheological analysis. The apparent activation energies of flow were calculated by the Arrhenius equation.
