Abstract

The use of nano fillers is a good strategy to improve the properties of biopolymer-based packaging films. The present study prepared ZEIN-based nano composite film containing MONTMORILLONITE using the solvent casting method. Mechanical, barrier, and thermal properties of the film were investigated. The x-ray diffraction patterns indicated that the composite film has an exfoliated structure. The results showed that the MONTMORILLONITE significantly improved the mechanical, barrier, and thermal properties of the ZEIN film. The highest elongation (9.65%) and tensile strength (22.62 MPa) were obtained for the ZEIN nano coposites containing 0 and 10% MONTMORILLONITE, respectively. Increasing the MONTMORILLONITE content from 0% to 5% decreased the water vapor permeability of the ZEIN film from 1.73 to 1.23 (28%). This parameter significantly increased (1.93) in film containing 10% MONTMORILLONITE. The thermal degradation temperature of ZEIN film increased (from 353 to 373 °C) by increasing the MONTMORILLONITE content from 0% to 10%. The results revealed that a small amount of MONTMORILLONITE can improve the mechanical and barrier properties of ZEIN film, although uniform dispersion of MONTMORILLONITE in the ZEIN network is essential to improving the properties of the film.
