Abstract

Thin electro-conductive CuxS films were deposited on plastic substrate from solutions containing copper chloride, thiourea (TU), sodium hydroxide, ethylenediaminetetraacetic acid disodium salt (EDTA), and polyethylene glycol (PEG) as surfactant. On the surface of CuxS film a layer of nickel was electrochemically deposited. The influence of etching treatment in acetone: water solutions and chromic mixture respectively on the electrical resistance of the obtained films was studied, as well as the influence of nickel deposition. After the deposition of nickel the electrical resistance of obtained multilayered composites decreased more than 5 times. The technique of deposition of an intermediate layer of copper sulphide in order to obtained a conducting plastic is preferable to classical technology, since the number of stages is reduced, and the necessity of using noble metals (Ag or Pd) is eliminated..
