Electrosynthesis of polyacrylic/polypyrrole composites: Formation of polypyrrole wires [PDF]

Synthetic Metals, 1999
Abstract A new preparation method is reported for the synthesis of conducting polypyrrole nanowires. This two-step all-electrochemical method consists in the cathodic grafting of a thin polyacrylate film on a carbon electrode, which is then used as an anode for the electropolymerization of pyrrole.
