'Characterization of Biodegradable Blends of PHBV/Tannin and PHBV/Lignin of sugarcane bagasse'

摘要

It was obtained blends with the lignin macromolecule of lignin of sugarcane bagasse with the polymer PHBV (50%/50%) and tannin with PHBV in films and in a Haake instruments. The thermal analyses equipment revealed that the produced blends possessed very similar thermal properties as PHBV, indicating that there is not interaction between the polymer (PHBV) and the macromolecule (Lignin) used. This was confirmed in the analyses of MEV, where the presence of emptiness was observed among the interfaces of the polymeric ones, concluding that the blends is immiscible.
