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.
