Hot Water Extraction of Corncob Hemicelluloses to Prepare Composite Films
Abstract:
In this study, corncob hemicelluloses were extracted by hot water to investigate its potential for film production. Extracted hemicelluloses were mixed with PVA 30 wt%, the prepared films had a smooth、uniform and continuous surface and dense cross section without the phase separation, as characterized by SEM. Besides, the mechanical properties and thermal characteristics tests showed that the films had a tensile strength of 4.6 MPa, elongation at break of 6.4%, and a nice thermally stability.
