an amido bonding of the polymer layer using
electrode surface anchor groups.
The following polymer materials are used for
the modification of electrodes:
redox polymer (polyviologene,
polyvinylferrocene, etc.)
polymers (poly-4-vinylpyridine,
polyvinylsulfonic acid, polyacrylonitrile,
etc.) that can form metal complexes and
immobilize redox active species through
columbic interaction
polymers (polycarbonate, polyurethane,
etc.) that enable selective ion/gas
permeation
conducting polymers.
Although examples of inorganic polymer-coated
electrodes are limited, Prussian blue,
heteropolyacid, clay film etc. can be utilized as
modification substances. The polymer-modified
electrodes have wide applications for fuel cells,
capacitors, display materials, biosensors, ion/
gas sensors and asymmetric synthesis, and
therefore they are currently being intensively
studied.
5.5 Paired Electrosynthesis
Electrosynthesis involves the simultaneous
occurrence of both reduction at a cathode and
oxidation at an anode. In a typical inorganic
