A Biodegradable Composite of Poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with Short Cellulose Fiber for Packaging

The problem of improper disposal polymeric waste is increasingly in present. Thus, the use biodegradable polymers a good alternative, especially for packaging. Compostable and such as PHBV can be completely degraded, making them ideal. But short processability window fluid instability an important drawback to wider application this polymer pure form. Production composite materials has been indicated possibility using polymer. One source filler cellulose, because besides being widely available from agroindustrial waste. In context, present work reports formulation rigid packaging with cellulose An analytical mill was used promote dispersion fibers. general, fibers increased Vicat softening point matrix. There were more crystalline structures, according DSC, decrease impact strength, probably due crystallinity agglomerate formation. microscopic analysis greater surface roughness increase fibers, resulting contact angle.
