Computational and experimental analysis of functional by Oleksandr V. Reshetnyak, Gennady E. Zaikov

By Oleksandr V. Reshetnyak, Gennady E. Zaikov

This book seems on the synthesis of polyaniline through diversified equipment, less than diversified stipulations, for numerous functions, and provides experiences of its houses by means of a variety of the fashionable physic-chemical tools. The e-book presents a complete research of experimental effects from the perspective of the correlations within the triad synthesis conditions–structurephysico–chemical homes. It combines the results of experimental investigations and unique method of the outline of physical–chemical and electrochemical phenomena at interface surfaces, exhibiting a power of such phenomena at the utilized facets of the polyaniline and nanocomposites on its foundation purposes.

52 V for meta-anisidine. Such impact of the position of substituent is true for different concentrations of electroactive monomers, and for different scanning rates of the potential electrode. 01 M initial concentration of monomer, the oxidation of ortho-anisidine takes place in several stages, as shown by the presence of three peaks of the oxidation current on the cyclic voltammogram (Fig. 11a), similarly as in the case of aniline (Fig. 1). 80 With each next cycle of the potential scanning ,the values of redox currents increase, which indicates the accumulation of the polymer and its subsequent conversion on the electrode surface,70 so, the anisidine unlike nitro-derivatives of aniline capable to form of homopolymers.

59,61 However, often the method of electrochemical polymerization is used due to the opportunity to get thin polymeric layers on the surface of the conductive substrate. It has been reported about obtaining of PAn on the platinum electrode during its polarization under potentiodynamic62 or galvanostatic63 conditions in both aqueous62–64 and organic65 media. In all cases, the structure and properties of the polymerizates differ significantly, mainly due to varying degrees of protonation of nitrogen atoms in the polymeric chain.

1). 574 electrons move from 2s to 2p level. This transition takes place mainly on 2pz level due to the same type of symmetry (axial) for s- and pz types of orbitals. 108 of elementary charge). 199 of elementary charge. 795 of elementary charge (cation-radical II and dication III, respectively). 2 ANALYSIS OF THE STAGE OF RECOMBINATION OF INITIAL RADICAL PARTICLES The next stage of the transformations during an oxidative polymerization of aniline is the formation of dimers as the result of recombination of initial radical products of the aniline oxidation, namely particles II, IV, VI, and VII.
