“…Use of these materials is potentially feasible in technological applications such as display devices, rechargeable batteries, electromagnetic shielding, sensors, and Schottky diodes. [1][2][3][4][5][6][7] At present, polyanilines (PANI) doped with various protonic acids are the most promising intrinsic conducting polymers, due to their relatively high environmental and thermal stability and of course their simple and economical synthesis routes. 8,9 The great potential of PANI is, however, shrouded by some of its disadvantages, such as insolubility, infusibility, and hence nonprocessability.…”

Poly(N-methylaniline) (PNMA) doped with p-toluenesulfonic acid (PTSA) was prepared chemically. Polymer synthesis was optimized for different dopant-tomonomer and oxidant-to-monomer ratios. The polymer was characterized by Fourier-transform infrared (FT-IR) and ultraviolet-visible absorption (UV-Vis) spectroscopy. The dependence of direct-current (DC) conductivity on temperature was studied in the range from 20 K to 300 K. The conductivity was found to follow the variable-range hopping (VRH) model of charge transport in the higher temperature range, while showing deviation at low temperature. The temperature dependence of the DC conductivity and activation energy data are indicative of the existence of both VRH and mixed conduction for various doping ratios in poly(N-methylaniline).

Poly(o-toluidine) (POT) and poly(2-chloroaniline) (P2ClAn) emeraldine salts were synthesized chemically by using formic (HCOOH), acetic (CH 3 COOH), propionic (C 2 H 5 COOH), and boric (H 3 BO 3 ) acids. Ultraviolet-visible absorption spectra (UV-Vis) analysis results indicated that POT has the better protonation effects than P2ClAn. Among the POTs synthesized using the four different acids, POT(H 3 BO 3 ) showed the least protonation effect. The conductivities of prepared polymers were measured by a four-probe technique. The highest conductivities were obtained in POTs synthesized by using formic, acetic, and propionic acids. Magnetic susceptibility measurements of the polymer salts were analyzed by using Gouy scale and it was found that POT(CH 3 COOH) and POT(C 2 H 5 COOH) salts are of bipolaron structure; other polymer salts are of polaron structure. The characterization of the polymers were investigated by Fourier infrared spectroscopy (FTIR), UV-Vis, thermogravimetric analysis, and scanning electron microscopy. It was observed from UV-Vis spectra of the emeraldine salt of POT that wavelengths belonging to 3 * transitions shifted to shorter wavelengths with increasing pKa values of acids. POT and P2ClAn synthesized in four different protonation media decomposed with three-step and three-or two-step weight loss, respectively.
