文摘

Recently, growing interests have been focused on biodegradable films from natural macromolecule, especially great efforts have been made to prepare composite films of xylan with other polymers to improve mechanical properties. In this work, we developed composite films of polyvinyl alcohol (PVA)/xylan with enhanced mechanical properties, the high hydrophobicity and the high UV shielding performance by an addition of TiO2. Influences of different crystal forms of TiO2 on the functional properties of composites films such as hydrophilicity/hydrophobicity, water vapor permeability, mechanical properties, solubility and UV transmittance were comparatively investigated. SEM and TGA were used to characterize the morphology and thermal stability of composite films. Results showed that rutile TiO2 could greatly improve the mechanical properties such as tensile strength (TS). When the amounts of rutile TiO2 and glycerol was 2 and 10?% based on the weight of PVA and xylan, TS reached to 30.73?MPa and the elongation at break (EAB) was 192.9?%, correspondingly to 115.5° of contact angle for PVA/xylan composite films. PVA/xylan composite films containing TiO2 had the high UV shielding performance. Therefore, these composite films with excellent properties could have the promising application for food and fruit packaging as preservative films.
