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...
