The electrochemical polymerisation of 2-and 4-aminobenzenesulphonic acids (orthanilic acid and sulphanilic acid) in sulphuric acid solution and co-polymerisation of mixtures of aniline and acid monomers, have been systematically investigated. The polymers formed have been characterised voltammetrically. Further evidence concerning the polymer structure and chemical composition has been obtained by IR spectroscopy and scanning electron microscopy (SEM). #

“…chloro or nitro groups such as in Refs. [38,43,44]; both of these types of substituent lead to lower conductivity than polyaniline itself. The third type of substituent involves introduction of acidic groups in the benzene ring, which directly influence the acidity constants of the amine groups and can lead to a decrease in the pH dependence.…”

The influence of pH on the electrochemical behaviour of conducting polymer films electrosynthesised from aminobenzoic acids and aminobenzenesulphonic acids was investigated by voltammetric and electrochemical impedance studies in sulphuric acid solution, acetate buffer and neutral phosphate buffer. The change in electrochemical behaviour with increasing pH is significantly less for poly(aminobenzenesulphonic acid)s and poly(aminobenzoic acid)s than for polyaniline. Polymer films made by electrosynthesis of mixtures of these monomers with aniline have also been analysed by the same techniques. Experimental results obtained over this pH range are interpreted in the light of previous studies carried out on these polymers in strong acid solution. #

“…Conducting polymers have become a popular basic material for advanced applications including plastic batteries, EMI shielding, electrochromic displays and sensors [1][2][3][4][5][6][7]. Among conducting polymers, polyaniline (PANI) has been extensively studied for its environmental stability in the conducting form, ease of synthesis, low cost and high conductivity.…”

“…It has also been proposed that the incorporation of side groups into the main chain [12], grafting of the conducting PANI chain to a non-conductive polymer [13] and electrochemical polymerization of aniline in a polymer matrix [14] improve their processibility and thus broaden their applicability. A large amount of PANI-inorganic composites like PANI/V 2 O 5 [15], PANI/TiO 2 [16][17][18], PANI/CdS [19], PANI/graphite oxide [20] and PANI/clay [21,22], etc have been synthesized and studied to enhance the overall Silver sulphate, ammonium persulphate, HCl and H 2 SO 4 were used as received. Double distilled water was deionized by Millipore used throughout the studies.…”

Polyanilines are synthesized by free radical chemical oxidative polymerization of aniline & o-toluidine using ammonium persulphate as an oxidant in protonic acid medium. These polymers have been introduced into polystyrene sulphonic acid (PSSA) in 2:1, 1:1, 1:2 compositions for the preparation of composite materials. The composite samples so obtained are thermally characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction, and FTIR spectra. The incorporation of polymer in PSSA has been endorsed by FTIR analysis. TGA data reveals that the (Polyaniline/Polystyrene sulphonic acid) PANI/PSSA (2:1) and (Poly o-toluidine/Polystyrene sulphonic acid) POT/PSSA (2:1) composites show better thermal stability than their 1:1 and 1:2 counterparts. Steric hindrance of -CH 3 group present in ortho position and sulphonic acid group of PSSA affects the thermal behaviour of composites. Two-step transitions are clearly reported from the DSC thermograms of polyanilines/PSSA composites and non-reversing chemical cross-linking reaction was further confirmed by X-ray diffraction and DSC thermograms.
