Solid state (PEO+NaClO3+Plasticizer) polymer electrolytes have been prepared by using solution casting technique. In this technique poly (ethylene oxide) (PEO), NaClO3 salt and Dimethyl Formamide(DMF) has been used for the preparation of polymer electrolytes. Using (PEO+NaClO3+Plasticizer) polymer electrolyte, the electrochemical cells have been fabricated for various compositions ratios of
(90:10), (80:20) and (70:30) of PEO and NaClO3. The discharge characteristics of the cell were monitored under a constant load of 100kΩ at RT. Using various compositions ratios of theses polymer electrolytes carbon monoxide gas sensor have been fabricated. The sensitivity of theses sensor has been verified at different gas concentrations and also at various temperatures
