Novel biodegradable composites based on poly(3-hydroxybutirate-co-3-hydroxyvalerate) (PHBV) and
different contents of purifi ed alpha-cellulose fi bers (3, 10, 25 and 45%) were prepared by melt blending
and characterized. The composites were characterized by scanning electron microscopy (SEM), wide-angle
X-ray scattering (WAXS) experiments, thermogravimetric analysis (TGA), differential scanning calorimetry
(DSC), dynamic mechanic analysis (DMA) and Shore D hardness measurements. Disintegrability under
composting conditions was studied according to the ISO 20200 standard. Morphological results showed that
high dispersion of the fi bers was achieved during mixing. Good adhesion on the fi ber-matrix interface was
also detected by SEM. The addition of low and medium cellulose contents did not result in lower thermal
resistance with respect to the neat PHBV. A reinforcing effect of the cellulose fi bers was detected in all samples,
this effect being more pronounced at high temperatures. The composting results show that the addition of the
fi bers did not affect the disintegrability of the PHBV, and thus compostable “green” low-cost PHBV/cellulose
composites can be obtained. [-]
