ABSTRACT:
Polypyrrole films are produced by electrochemical polymerization of a pyrrole, or a mixture of a pyrrole with other comonomers, in an electrolyte solvent in the presence of a conductive salt, by a continuous process wherein the pyrrole polymer is deposited in the form of a film on anodic material which has a sheet-like structure and is passed continuously through the electrolyte solution.
As shown in FIG. 1, this procedure can be carried out in an electrolysis vessel (1) which contains the electrolyte solution (2), a cathode (3) which dips into this solution, and, as the anode, a rotating cylindrical roller (4) which is partially or completely immersed in the electrolyte solution (2); the polypyrrole film (6) is deposited on the anodic surface (5) of the cylindrical roller (4), and is subsequently removed therefrom.
