The research on biopolymers and its derivatives has increased much attention towards the researchers in preparing a novel material. The biopolymers and its derivatives have vast applications due to its biodegradability, non toxicity and biocompatibility. The present study aimed to synthesis and characterizes novel chitosan Schiff base compounds using vanillin and O-vanillin. The prepared compounds were characterized under advanced analytical tools such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction studies (XRD), Thermal analysis (TGA and DSC) and SEM analysis. The results of FT-IR studies clearly indicate that chitosan Schiff base complex were effectively formed during blending. From the results of the XRD pattern, the change in crystallinity of the samples was elucidated. The thermal stability of the polymer complex was determined from the TGA and DSC studies. The SEM images showed the increased porosity of the chitosan derivatives. ______________________________________________________
