Study of room temperature LPG sensing behavior of polyaniline thin film synthesized by cost effective oxidative polymerization technique

Preparations, Properties, and Applications of Polyaniline and Polyaniline Thin Films—A Review

“…The cleaned glass substrate is placed vertically in the mixed reactants for 1 h to announce the PANI film [ 82 ]. The thickness of the thin film is 220 nm [ 83 ].…”

Enhanced LPG sensing-performance at room temperature of poly(o-anisidine)–CeO2 nanocomposites

“…Metal oxides 5,[8][9][10][11][12][13] and conducting polymers have been used as sensing elements for various LPG sensing applications. 14 However, metal oxide-based sensors work efficiently at high operating temperatures, typically in the range of 200-500 C, which increases power consumption, reduces sensor life and limits the portability. 15,16 This disadvantage impedes their practical usage in many real time applications.…”

“…have been studied, hardly any attempt has been made to investigate their LPG sensing properties. More recently, Birajadar et al 14 studied the room temperature LPG sensing behavior of PANI thin lms synthesized by a cost-effective oxidative polymerization technique. The PANI thin lm showed the highest response of 22 at 300 ppm with response and recovery times of 42 and 80 s, respectively.…”
