Effect of sugar palm fibers on the properties of blended wheat starch/polyvinyl alcohol (PVA) -based biocomposite films
Published 2023“…It has been found that reinforcing plasticized starch/PVA matrix with palm fibers has considerably enhanced physical properties, the density of the polymer declined to 1.21 g/cm3 with untreated fibers and to 1.32 g/cm3 with treated fibers, which created a lighter weight bioplastic, and a reduction occurred in water absorption (for example 3% of treated fiber showed 143% absorbed water after 30 min immersing in water) and water solubility. When compared to the films without fibers filler, films reinforced with fibers demonstrated a c3onsiderable improvement in the crystal profile; at 9% fiber load, it improved over double. …”
