In this paper, zein-based films with the addition of shellac were synthesized by lamination on the existing dry zein film (L samples) and by adding shellac alcohol solution during the synthesis of zein film in a ratio of 50-50 by casting process (M samples). Zein films without the addition of shellac were designated as control samples. Physico-chemical (thickness, moisture content and solubility), mechanical (tensile strength and elongation at break) and barrier characteristics (water vapor permeability) were examined for all samples.

Energy-dispersive X-ray diffraction is applied to investigate double-layer PBCO/YBCO thin films deposited by laser ablation. The merits of this technique for the structural study of films are discussed. It is shown that the rocking curves of the Bragg reflections of a film along thecdirection can be simultaneously collected, allowing the accurate evaluation of its angular spread. A systematic displacement of the rocking curves of the film with respect to those of the substrate was found, revealing a slight divergence of the growth direction from the normal to the substrate surface.

This was also found to correspond to an increase in the glutamate content on the PPy film surface.

The aim of this paper was to investigate the effects of cross-linked reaction on physicochemical properties of chitosan film by using genipin as cross-linker agent. Series of chitosan film samples with different amount concentration of genipin loaded (0-3 wt %) were prepared and characterized. The physicochemical properties of films were evaluated by Fourier Transform Infra-red (FTIR), UV-vis spectroscopy, Oxygen Transmission Rate (OTR), Scanning Electron Microscopy (SEM), water vapour and tensile test.
