Electrochemical formation of polypyrrole films on YBa sub 2 Cu sub 3 O sub 7- x. Technical report

OSTI ID:5555777
Aqueous electrochemical processes at the surface of the high-temperature superconductor YBa{sub 2}Cu{sub 3}O{sub 7-x}, including deposition of silver and magnesium, have been reported. This superconductor dissolves spontaneously under acidic conditions, and barium dissolves and oxide films form during anodization in neutral and basic electrolytes. An additional complication for electrodeposition of metals onto YBa{sub 2}Cu{sub 3}O{sub 7-x} is the competing reduction of the substrate. We report here the electrodeposition of polypyrrole from acetonitrile (MeCN) onto YBa{sub 2}Cu{sub 3}O{sub 7-x}. Since polypyrrole is formed by oxidation of pyrrole, the substrate is not reduced at the potentials employed. For comparison, deposition of AG from MeCN is also discussed.
