Structural, electrical, optical and gas sensing properties of MgTiO3-B doped polyaniline thin films

Abstract

The structural, electrical, optical, and gas detecting properties of porous MgTiO3-B doped thin films have been diagnosed by a chemical spray pyrolysis process, thin films were formed by changing the mass fractions of MgTiO3-B doped polyaniline (20%, 30%, 40% and 50%). The films were set aside at 250 °C and the precursor solution was made by dissolving magnesium chloride (MgCl2) in ethanol and in addition with 5% boric acid also PANI (polyaniline) in equal amounts (1:1). UV-vis Spectrometry, SEM, XRD and voltage-current measurements were used to describe the deposited films. H2S gas was utilized to investigate the behavior of gas sensors.
