Abstract

Electrochemical copolymerization of aniline with m-phenylenediamine (MPD) in sulfuric acid solution was investigated by cyclic voltammetry. At a high molar fraction of MPD (above 0.5), a strong inhibition of electropolymerization was found. Copolymerization was found to be possible only at low MPD to aniline molar ratio. The first redox couple of leucoemeraldine to emeraldine transition for a copolymer has a midpoint potential of 0.33 V versus AgAgCl and is shifted by about 0.2 V to the positive direction. The potential range, where an emeraldine form of copolymer exists, is narrower (0.37 V), as compared to polyaniline (0.65 V). A great current peak in the middle potential region was observed for a copolymer. Also, the memory effect of the bilayer structures of both polymers was studied.

      Poly (p-aminophenol-co-o-phenylenediamine) was synthesized by in situ electropolymerization technique followed by its composite formation with ZnO on Au electrode, which revealed high electron transfer rate [145]. Copolymerization of many conjugated monomers via electrochemical synthesis has been done widely in which aniline has been copolymerized electrochemically with m-phenylenediamine [146], p-phenylenediamine [147], o-toluidine [148], 2-amino-4-hydroxybenzenesulfonic acid [149], o-ethoxyaniline [150], 4,4′-diaminodiphenyl sulfone [151]. Copolymers of EDOT with pyridine [152], indole [153], thiophene [154,155], carbazole [156,157], pyrrole [158,159], and copolymers of o-phenylenediamine with aniline [160], o-toluidine [161], m-toluidine [162], o-phenitidine [163], o-methylaniline [164], diphenylamine [164], o-aminophenol [165,166], 1-amino-9,10-anthraquinone [167] have also been reported.

      P(mPD) homopolymer is considered to be completely insoluble in most organic solvents including NMP, DMSO and H2SO4 which are considered to be good solvents of polyaniline polymers [45]. However, to improve the solubility of P(mPD) but simultaneously maintain partial ladder structure and original functionalities and provide additionally novel interesting performances, various aromatic amines such as aniline, anisidine and xylidine have been utilized as comonomers [2,27–29,47,48], and modified copolymers have been obtained [49,50]. Unfortunately, the improvement in the solubility of copolymers is negligible.

      Duic et al. studied the influence of mPDA additions on the morphology and on the catalytic effect of polyaniline [20]. Copolymers of aniline–mPDA were prepared by electrochemical method for different purposes [21–23]. In this study, we will add small amount of mPDA to the emulsion solution of aniline monomers in the presence of both stronger acids of DBSA and HCl to modify the morphology of the PANINT backbone from straight to branched, which was found to terminate the chain propagation unexpectedly with the formation of chain end phenazines characterized by IR spectra.

      Copolymerization of aniline with substituted anilines bearing various functional groups leads to copolymers, which show electrochemical characteristics considerably different from those of the respective homopolymers [21–25]. Several reports are available on aniline or substituted aniline-based copolymers [26–30]. In many cases the copolymers exhibit better properties, in terms of their solubility in common organic solvents, electrochemical stability and electroactivity in solutions of high pH values, than the homopolymers [31–39].
