Carnauba and Rhea Americana Eggshell Powder Incorporation in PHB Bionanocomposites

Abstract:

In this work PHB poly (3-hydroxybutyrate) bionanocomposites with carnauba or emu eggshells (rhea americana), in amounts of 1 to 3 % wt%, were obtained by solution intercalation. Neat PHB solutions were prepared at room temperature under constant stirring for 3 hours and at rest 24 hours. The solution was then heated to 80°C and stirred for 3 hours before filler addition. Polymeric films were obtained by casting and solvent evaporation at room temperature. The filler were characterized by X-ray diffraction and thermal analysis and the films were characterized by X-ray diffraction, scanning electron and optical microscopies. System morphology was dependent on filler identity.
