Starch - Cellulose ether films: Microstructure and water resistance
Arık Kibar, E. A., Us, F.
Abstract:
In this study, composite films of corn starch, methylcellulose and carboxymethylcellulose plasticized by glycerol or polyethylene glycol (PEG) were prepared and the effects of blending level as well as the plasticizer type on the microstructure, water vapour permeability (WVP), opacity and solubility properties were investigated. SEM observations showed homogeneous matrix of glycerol plasticized films and it was taken as an indicator of structural integrity. PEG plasticized films exhibited discontinuous surface, and this was attributed to phase separation.
