Biodegradable polymers are important due to problems caused by the long life cycle of synthetic polymers. A biodegradable polymer of high commercial and academic interest is the poly (3-hydroxybutyrate-co-3-hydroxyvalerate), PHBV. The addition of carbon nanotubes (NTC) in the PHBV matrix to improve its properties (thermal, mechanical, morphological and optical properties) has been addressed in numerous papers. However, the effects of NTC addition on biodegradation are poorly known. Therefore, this project aims to evaluate the biodegradation effects of adding 1% e 2% (m/m) of NTC in the PHBV matrix. The samples of PHBV/NTC nanocomposites will be made by casting. The respirometric system method in aqueous and solid environments, as well as measurements of mass loss over the time, will be used to monitor the biodegradation. Morphological changes in the PHBV/NTC nanocomposites will be evaluated by scanning electron microscopy (MEV).
