The electro-oxidation of 3-amino-1,2,4-triazole on
a copper substrate in an alkaline methanol solution
produces a homogeneous and adherent polymer film
[83]. The thickness of the polymer film is about a
few µm. However, the current efficiency of the elec-
tropolymerization process is weak because of the for-
mation of oligomers and the oxidation of the elec-
trolyte.
Triphenylphosphine suppresses the formation of the
surface polymer complex, because a soluble complex
is formed. This leads to ...
