Films were prepared from aqueous dispersions of these cross-linked polymer blend at three different concentrations (3, 4 and 5%), by solvent casting method. Characterization of the films included thickness, surface morphology, water uptake, water vapor permeability (WVP), tensile strength measurements and enzymatic digestion. The cross-linking allowed to obtain films with improved mechanical properties and reduced WVP. The high resistance to enzymatic digestion exhibited by these films represents a promising approach to their application in the development of colon drug delivery systems.1354-1359engThicknesswater uptakewater vapor permeabilitymechanical propertiescontrolled releasecolonPreparation and characterization of free films of high amylose/pectin mixtures cross-linked with sodium trimetaphosphateArtigo10.3109/03639045.2011.650863WOS:000309453100009Acesso restrito5361569184579557
