Polyaniline (PANI) is one of the representative conductive polymers due to its huge electrical conductivity, process capability, tunable properties, high environmental stability in addition to a comparatively low cost (Bhadra et al. Recently, milder methods have been developed, including the use of lithium bromide as a catalyst and an improved procedure involving the use of microwave irradiation.[7][8][9]. A standard solution of 0.06 mM K4[Fe(CN)6] in 0.1M KCl was used as an electrolyte, in order to study the Fe(II) / Fe(III) redox current peaks at various concentrations, pH, scan rates, measurement of diffusion coefficient, stability and reliability on the modified electrode. [11] These two researchers did not collaborate with each other, but instead independently developed very similar procedures starting from an aromatic ketone structure with an excess of some aniline and ultimately producing an product. The resistivity changes versus pH changes show linear dependence by increasing the resistivity of the nanosensor with decreasing the pH of the water. Stahl believes that the iridium photocatalyst loading might have to be reduced too. To overcome this limitation, Leonori and his team, in a collaboration with the pharmaceutical company AstraZeneca, replaced the aromatic starting materials with single-bonded rings containing a C=O group, called cyclohexanones. Leonori points out that the new procedure is meant to fill the gap where common cross-coupling methods don’t work. A versatile method for making anilines – important aromatic molecules used in drugs and agrochemicals – has been developed by researchers in the UK.1 The new approach, which uses non-aromatic precursors and light, bypasses some of the frequent selectivity issues of aromatic chemistry and enabled the scientists to synthesise compounds that can’t be made using traditional cross-coupling reactions. By adopting the new electrode structure coupled with a gas channel, a low temperature DBD is successfully implemented in a SPP, for the first time, thus inducing an effective interaction between the Ar plasma and aniline monomer. voltammograms during polymerization of aniline are observed. The, polymerization of aniline occurs on an electrode made, of inert conducting material.
