Characterization and Biomedical Applications of Electrospun PHBV Scaffolds Derived from Organic Residues.

This study explores the characterization and application of poly(3-hydroxybutyrate--3-hydroxyvalerate) (PHBV) synthesized from organic residues, specifically milk and molasses. Six PHBV samples with varying 3-hydroxyvalerate (3HV) content (7%, 15%, and 32%) were analyzed to assess how 3HV composition influences their properties. Comprehensive characterization techniques, including NMR, FTIR, XRD, DSC, TGA, and tensile-stress test, were used to evaluate the molecular structure, thermal properties, crystalline structure, and mechanical behavior.
