“…The similar type of phenomenon was observed in camphor sulfonic acid-doped polyaniline-tin oxide nanocomposites [34]. In addition, the formation of polarons or bipolarons in the PPy-WO 3 nanocomposites takes place with the delocalization effect of doping process thus, enhancing the conductivity of DBSA-doped PPy-WO 3 nanocomposites [35][36][37]. The variation of conductivity with composition is shown in Fig.…”

“…Conducting polymers with a polyaromatic back bone have received a great deal of research attention, such as polypyrrole, polyaniline, and polythiophene. They have been already in extensive use in order to immobilize desired chemical species for development of technological applications [22][23][24][25][26][27][28][29]. PANI is unique in the family of the conducting polymers due to its reversible doping/de-doping properties based on acid/base reactions [30,31].…”

Poly(aniline-co-o-anthranilic acid) (PANAA) and its nickel composite (PANAA-Ni) are successfully prepared based on oxidative chemical polymerization via two comparative in situ and ex situ polymerization methods. PANAA copolymer contains aniline, and o-anthranilic acid moieties, were doped with different concentrations of nickel ions. The ratios of aniline, o-anthranilic acid, and nickel chloride were (1:1:0.5) and (1:1:1), respectively. The effect of nickel moiety on the properties of polyconjugated polymers, and their spectral characteristics (UVVis absorption spectra, FTIR, thermal stability) were recorded. TGA analysis confirmed that the poly(aniline-coo-anthranilic acid)/nickel (PANAA-Ni) composites, which were prepared by in situ or ex situ polymerization method, are more thermally stable than the pure PANAA copolymer. The XRD revealed that the pure and PANAA-Ni (prepared by ex situ polymerization method) is completely amorphous structure, while the PANAA-Ni composite (prepared by in situ polymerization method) is a mixture of crystalline and amorphous phases. The temperature dependence of dielectric constants (e r and e i ) as well as AC conductivity (r ac ) were investigated in the temperature range of 300-383 K and test frequency range of 0.1-100 kHz. All the tested samples showed semiconductor behavior. The values of thermal activation energies DE1 and DE2 for PANAA copolymer are calculated, and found to be in the range of 0.03-0.1 eV and 0.58-1.88 eV, respectively. We calculated DE1 and DE2 for PANAA-Ni composite, and we found their values in the range of 0.14-0.27 eV and 0.41-0.58 eV, respectively. Moreover, Nanocrystalline nickel oxide NiO powder was prepared by thermal decomposition route of (PANAA-Ni) composites, which was prepared by in situ polymerization method. The size of the obtained nickel oxide nanoparticle was determined by transmission electron microscope .

“…The presence of CSA is confirmed by the bands at 1039 cm -1 (SO 3-) and 1735cm -1 (C=O) [4]. The fact that the polymer is the protonated in the part by surface anions is demonstrated by the presence of the peak at 618 cm -1 , which is attributed to a stretching vibration in the surface anion [4]. Figure 2 shows FESEM image 30% CSA doped PANi-SnO 2 thin film.…”

The PANi-SnO 2 hybrid nanocomposite based thin films doped with 10-50 wt % CSA were deposited on the glass substrates using the spin coating technique. The sensor response in relation to the CSA doping concentration and the gas concentration has been systematically studied. A significant sensitivity (91%) towards 100 ppm NH 3 operating at room temperature is observed for the 30 wt % CSA doped PANi-SnO 2 nanohybrid. The sensing mechanism of CSA doped PANi-SnO 2 materials to NH 3 was presumed to be the effect of p-n heterojunctions.
