Abstract: | This paper presents a review on a series of recent investigations focused on the understanding of the role of various factors
for the number, size, and location of the metal particles electrodeposited in conducting polymer (CP) layers. It is demonstrated
that the initial oxidation state of the CP layer and its surface and bulk structure play an important role for the location
of the metal particles. The use of metal anion complexes instead of the corresponding metal cations presents a helpful tool
for affecting the location and number of metal crystals. The involvement of special metal/polymer interactions in the metal
electrocrystallization process is another way for influencing the metal deposit. An alternative to the electrodriven deposition
is the electroless metal precipitation based on the reducing ability of the CP layers. This approach results in metal particles
deposition at the polymer surface and may be effectively controlled through parameters such as CP reduction charge, dipping
time, and concentration of the metal-plating solution. |
