The primary objective of this study is to provide comprehensive market intelligence on a global level of its one of the derivative chitosan, nanochitosan and its blend, the present study explore the synthesis of nanochitosan/polyvinyl alcohol a binary blend of different ratios (1:1), (1:2), (2:1) with glutraldehyde as a crosslinking agent. The prepared blends were characterized under advanced analytical aids such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction studies (XRD), Thermal analysis (TGA and DSC) for its physical and chemical properties studies.
