Effect of a magnetic field on surface structure of the electrode modified with aromatic polymer

abstract ctrode (platinum) was modified with poly (o-phenylenediamine) (PoPD) by electrochemical polymerization in the magnetic field (6T) and without the magnetic field (OT). The modified electrode (PoPD/Pt) surface was investigated using AFM. It was found that the flatness of the modified electrode surfaces was dependent on magnetic field direction. For electrode setup (1), a flat surface is observed. In case (2), the modified surface is very rough. The image of the electrode surface prepared with no magnetic field is the intermediate one between cases (1) and (2).
