Effect of ammonium thiocyanate on ionic conductivity and thermal properties of polyvinyl alcohol�methylcellulose�based polymer electrolytes

In this work, a polymer blend�based electrolyte system using polyvinyl alcohol (PVA) and methylcellulose (MC) in the weight ratio of 50:50 as hosts and ammonium thiocyanate (NH4SCN) as dopant salt has been prepared and characterized. Fourier transform infrared spectroscopy (FTIR) studies indicate...
