✦ Synopsis

Electrochemical deposition of polymer coatings makes use of electrolytic solutions, containing monomeric and/or polymeric starting materials . Under the influence of electrochemical processes physical or chemical transformation of the dissolved material leads to the formation of a solid film of 10 nm to 100 µm thickness on the electrode . Nucleation and precipitation may he rate determining processes and are discussed in greater detail, namely : (1) electrocoagulation of waterborne polymers . (2) Electrochemical coupling, in the case of anodic electropolymerization of (hetero) aromatics. The propagation step is an electrochemical one.

(3) Electrochemically initiated vinylpolymcriration . The propagation step is of chemical nature .

Combinations of these methods are also known. The most important practical application is corrosion protection of iron substrates.
