Abstract: This work deals with the electrical and optical response of poly (o-methoxyaniline) (POMA) thin films exposed to nitrogen and nitrogen with methanol. A low cost apparatus was developed for the optical assessment of the presence of methanol in an ambient It is shown that thick POMA films exhibits a wide optical absorption variation when in presence of methanol. It was observed that the optical absorption characteristics retum to the initial condition when methanol exposition ceases. Electrical response of a photoresistor to methanol showed larger relative variations but also presented large noise interference. A residual drift in the resistance is presented after every cycle and it need to be better evaluated.
