Poly(hydroxybutyrate) (PHB) is produced as intracellular storage materials by different types of microorganisms from renewable sources. Not only they are biodegradable and biocompatible, but they can also be produced by bacterial fermentation from renewable resources like cane sugar1. Films of PHB and its nanocomposites with the addition of 4% of different commercial clays (CNa+, C93A, C15A) were obtained by casting process1. Thermal behavior and crystallization kinetics were performed using a Perkin-Elmer Pyris 1 DSC.
