Indirect Bipolar Electrodeposition
Based on the principles of bipolar electrochemistry,
localized
pH gradients are generated at the surface of conducting particles
in solution. This allows the toposelective deposition of inorganic
and organic polymer layers via a pH-triggered precipitation mechanism.
Due to the intrinsic symmetry breaking of the process, the concept
can be used to generate in a straightforward way Janus particles,
with one section consisting of deposits obtained from non-electroactive
precursors. These indirect electrodeposits, such as SiO<sub>2</sub>, TiO<sub>2</sub>, or electrophoretic paints, can be further used
as an immobilization matrix for other species like dyes or nanoparticles,
thus opening promising perspectives for the synthesis of a variety
of bifunctional objects with a controlled shape
