A new H+ ion conducting polymer electrolyte has been developed by complexing NH4SCN in a polyethylene succinate matrix. XRD, IR and DTA studies have been carried out to understand the complexation. The values of various transferance numbers are: total tion ≈︂ 0.96, t ≈︂ 0.87, tanion ≈︂ 0.09, te/h ≈︂ 0.04. The complex impedance/admittance method has been used to study the bulk conductivity as a function of composition (i.e. NH+4/ESc ratio) temperature and relative humidity. The PESc:NH4SCN complex with NH+4/ESc ≈︂ 0.87 had the best conductivity (10—4 S cm—1) at room temperature.
