The electrocrystallization model is generally applied to study the gen
eration of a polymeric phase onto a metallic suface. The model require
s to distinguish the different characteristics of the metallic and pol
ymeric phases, as well as to state the heterogeneous nature of the ele
ctrochemical process. Electrochemical parameters are evaluated in the
potenciostatic formation of Polyfuran films (PFu)in order to analize t
he type of nucleation and growth.
