“…Since then, many papers reported the preparation of the self-doped polyanilines by the chemical copolymerization of aniline with o-aminobenzenesulfonic acid [15] and m-aminobenzenesulfonic acid, [16] and the electrochemical copolymerization of aniline with m-aminobenzoic acid, anthranilic acid, m-aminobenzenesulfonic acid (m-ABS), [17][18][19] and other monomers. [20][21][22][23][24][25][26][27] Among these self-doped polyanilines, poly(aniline-co-m-ABS) electrochemically prepared can retain the redox activity in the buffer solution of pH 9 at the scan rate of 25 mV s À1 . [18] Recently, the synthesis and properties of self-doped polyanilines have been reviewed extensively.…”

Summary: Polyaniline with two types of functional groups (sulfonated poly(aniline‐co‐o‐aminophenol), s‐copolymer) has been prepared by the electrochemical copolymerization of aniline and o‐aminophenol in sulfuric acid solution followed by sulfonation of the copolymer in the concentrated sulfuric acid. There are SO3H groups and OH groups in the s‐copolymer. The presence of SO3H groups on the polymer chain enables the s‐copolymer to possess intrinsic protonic doping ability. The OH group on the polymer chain can be oxidized and reduced reversibly. The shape of the cyclic voltammogram of the s‐copolymer is very similar to that of polyaniline in 0.2 M H2SO4 solution, in the potential range −0.20 to 0.80 V (vs. SCE). The results from cyclic voltammograms indicate only 22.8 and 31.6% decay of the electrochemical activity that was observed when the s‐copolymer electrode was transferred from the solution of pH 5.0 to the solutions of pH 10.0 and 11.0, respectively. Especially, there are still two pairs of redox peaks on the cyclic voltammogram of the s‐copolymer in 0.3 M Na2SO4 solution of pH 11.0 at the scan rate of 6 mV s−1. In this case, its usable potential range is 0.0–0.60 V. The s‐copolymer has a conductivity of 0.85 S cm−1, which is slightly dependent on pH when equilibrated with water. The spectra of FTIR, XPS, and ESR of the s‐copolymer are represented here.

“…The resulting copolymer film found to have both good conductivity and solubility in common organic solvents. Lately, copolymerization of aniline with N-methylaniline (Langer et al, 1993) and that with 3-aminophenyl-boric acid (Porter et al, 1990) have also been documented and also the electrochemical copolymerization of aniline with oaminobenzonitrile has been studied (Sato et al, 1994). These reports suggest that the copolymerization could provide us a convenient synthetic method to prepare new conducting materials with desired properties.…”

“…One of these methods is to substitute one or more hydrogen by the electron-donating groups, such as an alkyl, an alkoxy, an aryl hydroxyl, and an amino group, [7][8][9][10] or by the electron-withdrawing groups as halogen in an aniline nucleus, like a sulfo group, a carboxyl, an acyl, and a cyano group. [11][12][13][14][15][16][17] Many researches [18][19][20][21] have studied different properties of polyaniline and polyacrylonitrile by blending method, while few articles were investigated on the chemical synthesis to prepare acrylonitrile derivatives of polyaniline. Recently, Siddaramaiah 22 has reported a new method to synthesize poly(aniline-co-acrylonitrile) to improve processability of polyaniline, however, they did not mention the solubility of the copolymer in detail.…”

A novel copolymer based on aniline and N-bcyanoethylaniline was chemically prepared and characterized by a number of techniques including UV-vis, FTIR, ESR, XRD, and TGA. According to the systematic studies on the physical properties, it was found that the copolymers had excellent solubility in common organic solvents especially in DMF and pyridine, while the conductivity and yield decreased as the content of cyanoethyl group increased in the system. Moreover, an increase in the feed ratio of N-b-cyanoethylaniline induced a blue-shift of the absorption bands in the UV-vis and IR region and significant line broadening of ESR signals together with a reduction in spin density. The XRD patterns of the copolymers lost the characteristic diffraction peaks of emeraldine salt as the ratio of cyanoethyl group increased. The thermal stability of the copolymer was increased with increasing the feed molar ratio of N-bcyanoethylaniline.
