Optimization of Chitosan: Methylcellulose polyblend to obtain highly amorphous polymer matrix useful for ion transportation

Solid biopolymer blend systems consisting of chitosan (CH) and methylcellulose (MC) have been prepared in various compositions through the solution casting method and are characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The XRD data revealed that the blend composed of 30 wt.
