Abstract:
Earlier we have demonstrated the principal possibility to produce fullerene-containing coatings on metal electrodes by the electrochemical method and the dependence of their structure on the chemical composition of the working solution and experimental conditions. This work represents the results of investigations into thermal oxidation of electro-deposited fullerene-containing anodic coatings, the dependence of oxidation parameters on the composition of the working solution. Some electrolysis products have been investigated by IR spectroscopic and X-ray phase methods. Based on comparison of the obtained results, we have made conclusions about phase and chemical compositions of the substances investigated. The thermal parameters for oxidation of the coatings produced by electrolysis of TFE solutions with additives and without them are given. The dependence of the chemical composition of the coatings on the type of additive has been established. It has been shown that in heating the coating that was deposited electrically from the TFE solution fullerenes are sublimated and graphitized. IR transmission spectra of the electrolysis products that were produced from the TFE solutions with KBr or KOH additives and without them, and also diffractograms of the coatings that were deposited electrically from the TFE solution without additives and with KOH are represented. Analysis of IR transmission spectra and diffractograms confirms heterogeneity of the chemical composition of the coatings that were deposited electrically from the TFE solution with KBr or KOH additives. This solution is a mixture of fullerenes of the fcc lattice and fullerene-containing compounds. The coating that was deposited electrically from the TFE solution without additive comprises fullerenes of the fcc lattice and is a mono-phase system.
