(57) The subject of the invention is a blend material consisting of a conductive polydopamine
fraction doped with chloride ions and a conductive polypyrrole fraction doped with
chloride ions, deposited on a conductive surface (i.e. substrate electrodes).
The essence of the present invention is also the deposition procedure of the PDA-PPy
blend, which consists in the fact that the process of potentiodynamic deposition of
a polymer layer is carried out preferably on glassy carbon by electrochemical polymerization
from a dopamine solution as a functional monomer in the form of a dopamine-containing
solution with a concentration of 10-10 M - 1 M in the supporting electrolyte 10-3 M - 1 M KCl / NaCl / LiCl, with a potential linearly changed in the range from -
0.8 V to + 0.65 V, preferably in the range from - 0.5 V to + 0.5 V (vs. Ag/AgCl/Claq.-(3M)). On the prior obtained polydopamine layer on the conductive surface, pyrrole
electropolymerization is carried out by potentiostatic method from a solution of pyrrole
as a functional monomer in the supporting electrolyte 10-3 M to 1 M KCl / NaCl / LiCl, with a constant potential from the range of + 0.45 V
to + 1.2 V.
