Synthesis and humidity sensing properties of conducting poly(N-methyl aniline) doped with different acids

Study of Synthesis and Temperature Dependence of DC Conductivity in the Low Temperature Range for Poly(N-Methylaniline)

“…These bands are assigned to the p-p* transition of benzene rings in the first case and polaron bands in the last two cases. 23 The last two bands at higher wavelength arise due to the doping which is responsible for the enhancement of conductivity in polymers. This was further supported by the DC conductivity results.…”

Humidity sensing properties of poly(o-anisidine)/WO3 composites

“…Poly(o-anisidine) (POA) and poly(N-methylaniline) (PNMA), which are derivatives of PANI were also reported to be humidity sensitive by Kulkarni et al [9,10]. In these studies, they investigated the effect of acid dopants on the humidity sensing properties of POA and PNMA.…”

Gas sensors development using supercritical fluid technology to detect the ripeness of bananas

“…This fact may be attributed to ions mobility of the dopant substance entrapped into polymer chains by the weak van der Waals attracting forces. The low humidity influences the restricted mobility of the dopant ions, which are part of the polymer chains (Kulkarni et al, 2006). Thus, it seems quite interesting for practical applications that sensors prepared from RESS or precipitation are less sensitive to moisture than in situ preparation.…”
