Abstract

The magnetic field effects were investigated on the dendritic growth morphology in electrodeposition, electroless deposition and electropolymerization. The magnetohydrodynamic effect inducing convections in the solutions leads to spiral and compact growth patterns of the zinc electrodeposits. The Lorentz force acting on the elementary motions in the diffusion of ions leads to dense-branching morphology of silver electroless deposits with a smooth growth front. Dense-film growth of magneto-electropolymerized polypyrrole was considered to result from the effect of diamagnetic orientation. The magneto-electropolymerization was applied to the control of the electrochemical properties of the polypyrrole films.
