Abstract:
The molecular structure, morphology, and electrical conductivity of polypyrrole coatings deposited on an iron
chloride sublayer were determined. The changes in the molecular structure and electrical conductivity during heat treatment of
the synthesized polypyrrole layers were established. To effectively mitigate the degradation of polypyrrole coatings during
heating, the formation of a sulfate or phosphate passivation layer on their surface was proposed. The decrease in conductivity
during heat treatment and the increase in the threshold voltage, above which a conductivity increase is observed, during storage
are attributed to the chemical interaction between the copper electrode and iron chloride.
