Resumen:
Biodegradable polymers (BP) blending is an alternative approach to get new materials with desirable properties based on environmentally caring systems. Polyhydroxybutyrate (PHB) is a BP, obtained from renewable resources. Its melting point, brittleness, and low toughness, make PHB use difficult. Polycaprolactone (PCL), a synthetic BP, has a low melting point and is ductile at room temperature.  The physical mixture of these polyesters seems to be an alternative to produce materials to help sustainable development.  Previous work has shown that PHB and PCL are immiscible and that low loads of organo-modified clays change blends morphology in different immiscible polymer [1]. In present study, we portray the first results on the characteristics of PCL/PHB blend films and of PCL/PHB nanocomposite films as function of its composition.   Botana, A; Mollo, M: Eisenberg, P; Torres Sanchez, RM.
