Resumen:
During the last decade, many studies related to the crystallization of polycaprolactone (PCL) nanocomposites have been published and they have shown controversial results regarding the nucleating or retarding effect of PCL modified with several compounds: pure clays and/or functionalized with different chemical agents. The effects have been studied analyzing different experimental parameters as the changes on the crystallization temperature (increase or decrease), the crystallization rate (higher or lower), the effective energy barrier (increase or reduction) or the half-crystallization time (decrease or increase). In the previous studies, both effects (retarding or accelerating ones) were also demonstrated by the use of different theoretical models, such as Osawa, Avrami or Mo. The aim of the present work was to try to elucidate the dominating factors that affect the isothermal and no ?isothermal crystallization processes of PCL based nanocomposites.
