Abstract

Summary: Isothermal crystallization of nanocomposites of poly(p-dioxanone) and layered double hydroxides (unmodified or oganically modified) prepared by melt extrusion has been studied by Dynamic Scanning Calorimetry and Optical Microscopy. Although the nanoclay acts as a nucleating agent, the spherulite growth rate of the nanocomposites decreases due to the polymer chain mobility restriction induced by layered double hydroxides. In addition, it has not observed any change on the crystallization mechanism in presence of layered double hydroxides.
