Electrochemical preparation of conductive poly(N-alkylaniline)s with long N-alkyl chains using appropriate dopant anions and organic solvents

Study of Synthesis and Temperature Dependence of DC Conductivity in the Low Temperature Range for Poly(N-Methylaniline)

“…When PANI is N-methylated to form PNMA, it becomes more soluble in common organic solvents than pure PANI. 13 The doping reaction of PNMA with p-toluenesulfonic acid is shown in Fig. 1.…”

In situ conductance and in situ ATR-FTIR study of poly(N-methylaniline) in aqueous solution

“…The conductivity was measured to 5.7 · 10 À2 S m À1 of the emeraldine form of PNMA, in comparison to the value of 10 À7 S m À1 obtained for the same polymer in its nonconducting form. The dependence of the length of the N-substituted chain on the conductivity of the PANI derivatives was studied by Yano et al by measuring pellets made from the polymers with the four probe technique [13]. Kankare et al [14] proposed a theoretical model for the conductance of a growing conducting polymer layer on a double-band electrode.…”

“…The instrument design of various types of in situ conductivity measurements and their application on electrochemically synthesized conducting polymers, have been demonstrated in some publications [15][16][17][18]. However, there are only a few reports on the conductivity studies of PNMA [12,13,19,20]. In situ conductance measurements on PNMA carried out simultaneously with voltammetric measurements in an electrochemical cell have to the best knowledge of the authors, not earlier been reported.…”

Electrochemical Polymerization of Aniline

“…The obtained polymers exhibited similar electrochemical and UVbehavior to "ordinary" polyaniline, but their conductivities were remarkably lower, explained by the steric effects of the substituent (Şahin et al 2003). Various alkyl substituted anilines were electrochemically polymerized in both acetonytrile and dimethiylsulfoxide, their conductivities were also very low suggested that there were not in the typical state of the emeraldine salt (Yano et al, 2004). Successful electrochemical co-polymerization of aniline and pyrrole was also carried out in acetonitrile.…”
