This work reports the development and characterization of chitosan/ phosphomolybdic acid-based composite membranes. The prepared composite membranes were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), differential scanning calorimetry (DSC), tensile strength test, and thermogravimetric analysis (TGA). FTIR spectroscopy indicated the proper molecular interactions between chitosan and PMA. XRD spectroscopy indicated the semi crystalline nature of the composite membranes. DSC study showed the presence of single glass transition temperature (T-g) at 156 degrees C in the 20% PMA-doped membrane, which indicates the miscible nature of chitosan and PMA blend. TGA study indicates increase in thermal stability of the composite membranes as compared to pure chitosan. Mechanical properties of the composite membranes were found to be enhanced significantly.
