Abstract—Growth of solid polymer electrolytes is driven by their tremendous technological applications. Therefore, solid-state polymer electrolyte have been prepared by solution – casting method by using poly (ethylene oxide) (PEO), KClO₄ salt and Nano filler Al ₂ O₃. The complexation of poly (ethylene oxide) (PEO), KClO₄and Al ₂ O₃ have b een studied by using X-ray diffraction (XRD), IR and differential scanning calorimetry (DSC). Solid state electrochemical carbon monoxide gas sensors have been fabricated by using pol ymer electrolytes (PEO+ KClO₄) and (PEO+ KClO₄+Nano filler Al ₂ O₃) and studied their sensitivities at different temperatures, a nd at different carbon monoxide gas concentrations. From these studies it is concluded that nano filler added polymer electrolytes sensor have more sensitivity when compared to the polymer electrolytes without nano filler.

Index Terms—Polymer, poly (ethylene oxide), x-ray diffraction, gas sensor.
