Abstract
(PEO+KClO4) based polymer electrolytes have been prepared by using Solution casting technique. The pure PEO poly (propylene oxide) and alkali salt KClO4 is dissolved in methanol. PEO and appropriate amounts of the salt mixture taken in stoichiometry were separately dissolved in methanol and then two solutions were stirred together for about 24 hours. Aluminium tube was dipped in the solution and removed from that solution, then it was allowed for evaporation at room temperature. When this process was done several times, then the aluminium tube substrate carries a coating of polymer electrolyte. Using this substrate carbon monoxide gas sensor was fabricated and its characterizes were obtained. In this experimental investigation it was observed that, sensitivity of the gas sensor was raised with an increase in the composition of the salt in the polymer, temperature and carbon monoxide gas concentration

Key-Words / Index Term
polymer electrolytes, solution casting technique, gas sensor, sensitivity.
