Application of QCM technique in the kinetic study of polyaniline film formation in the presence of a constant (0.4 T) magnetic field

There are several types of aniline oligomers that can be formed in the early stages of aniline oxidation: linear oligomers with repeating units joined in para positions, and various branched and polycyclic oligomers, being the two most important groups. The fraction of these different oligomeric groups depends upon the reaction conditions of aniline oxidation. The aim of this study was to analyze the first products of the chemical and electrochemical oxidation of aniline at the (starting) pH 1 and 7, in order to specify the conditions of the formation of phenazine-like oligomers, and to test the theory that they have an important role in polyaniline film formation. We have confirmed that phenazine-like oligomers do not form at pH 1, neither in the chemical nor the electrochemical oxidation of aniline; however, they form in both chemical and electrochemical oxidation of aniline at pH 7. Phenazine-like oligomers are thus definitely not necessary intermediates for PANI film formation, not even in the chemical polymerization of aniline. Finally, the redox behavior of phenazine-like oligomers was demonstrated in a medium at pH 1.

Processes of film formation (0001) BaFe12O19 on sapphire with ferromagnetic "easy axis" directed along normal to substrate are investigated. Propagation of the beam of high-energy electrons during interaction with the (0001) BaFe12O19 film was studied depending on the angle of incidence of the beam. Deflection of sliding electron beam by magnetic field of (0001) BaFe12O19 film is demonstrated. It is shown that the presence of (0001) BaFe12O19 film on sapphire leads to the redistribution of cathodoluminescence in it mainly to the "red" region. The radiation associated with the film itself was not detected in the experiment.
