The present study explores the preparation of binary blend films of
chitosan and vanillin using solution casting and solvent evaporating
technique. The prepared binary blend films were analyzed by using
Universal Testing Machine (UTM), Scanning Electron Microscope
(SEM), FT-IR spectroscopy and Thermogravimetric analysis (TGA).
With increase in concentration (wt %) of vanillin, tensile strength
(Ts), young’s modulus (Ym) and elongation at break (Eb) has
displayed increased value compared to the pure chitosan film. The
SEM micrographs of binary films with different ratio showed smooth
homogeneous surface. The results of FT-IR study explains the
presence of good interaction between chitosan/vanillin films. TGA
confirms that, at lower temperature range blend films were stable.
This may be attributed to the effect of crystalline nature of vanillin in
chitosan films. The review of the study summarizes, the prepared
binary films can find applications in pharmaceutical drugs and in
food packaging applications.
