Humidity sensing with weak acid-doped polyaniline and its composites

Spectroscopic and electrical properties of polyaniline/CeO2 composites and their application as humidity sensor

“…Relative humidity inside the chamber was monitored by a standard precalibrated humidity meter. 24 Figure 2 shows the X-ray diffraction pattern for the composites having 50 wt % of cerium oxide in PANI. It is seen from Figure 2 that the cubic peak of CeO 2 indicates the crystalline nature of the composite.…”

Polyaniline-Doped Spherical Polyelectrolyte Brush Nanocomposites with Enhanced Electrical Conductivity, Thermal Stability, and Solubility Property

“…However, large-scale application of PANI is limited except for improving its insolubility and infusibility. Consequently, many studies have focused on the synthesis of PANI with suitably-modified structures by "doping" [17][18][19][20]. It is encouraging that the doped PANI not only possesses high electrical conductivity, but also has good solubility properties.…”

“…Conn, et al [17] developed a polyaniline/PtO 2 based selective H 2 sensor and reported that the conductivity of polyaniline increases with H 2 exposure, due to the formation of water. It is known that water present in the polymer takes part in charge transfer leading to an increase in the conductivity of polyaniline which is reversible [18][19]. Wang, et al [20] developed polyaniline intercalated MoO 3 thin film sensors and reported that the conductivity change is due to the reversible absorption of analyte.…”
