Magnetic alignment of polypyrrole layered structures by repeated redox cycles
A perchlorate-doped polypyrrole was processed by repeated redox cycles in a 0.1 M NaClO4 aqueous solution under a magnetic field applied parallel to the faradic current. The film that was initially isotropic underwent magnetic alignment. X-ray measurement revealed that the polypyrrole layered structures were aligned perpendicular to the electrode surface.
