Dr. Lawson et al., INORGANIC AND BIOLOGICAL ELECTRON-TRANSFER ACROSS AN ELECTRONICALLY CONDUCTIVE COMPOSITE POLYMER MEMBRANE, Chemistry of materials, 5(4), 1993, pp. 400-402
Electron-transfer reactions can be driven across polypyrrole-containin
g membranes because polypyrrole is both electronically and ionically c
onductive. This paper provides experimental proof of this concept. A p
olypyrrole composite membrane separates a solution of an electron dono
r from a solution of an electron acceptor. The polymer channels electr
ons and ions across the membrane so that a sustained transmembrane red
ox reaction occurs. Examples of both inorganic and biological transmem
brane redox processes are provided.
