摘要: The synergistic plasticization/compatibilization effect of poly(ethylene glycol)/glycerol is reported for poly(vinyl alcohol) (PVA)/chitosan blends. optimum concentration PEG was first determined by preparation and characterization PVA/PEG blends at different ratios (9:1, 6:1 3:1). PVA/chitosan blends, plasticized with PEG, glycerol, their combination, were also prepared characterized. Fourier transform infrared results suggested that enhances the compatibility This claim further confirmed morphological results. However, had a detrimental on crystallinity combination glycerol caused five-time enhancement in elongation break values as compared blend glycerol. antibacterial properties against E. coli evaluated. All all, high films along good mechanical could be beneficial wound dressing food packaging applications which need investigation.
