Abstract
Investigations were carried out into the processes of electrochemically initiated (co)polymerization (EIP) of acrylamide (AA) and/or acrylonitrile (AN) from acidic aqueous solutions on a steel cathode. The aim was to obtain (co)polymer films with given electroinsulating and corrosion protection properties. The kinetics of (co)polymer film formation were investigated using various electrochemical methods (constant current and constant potential electrolysis, cyclic voltammetry, double-layer capacity measurements) and ellipsometry. The electrical properties of the films formed were studied (ex situ) by measuring their impedance (Z) and phase angle (θ) as a function of frequency. It was shown that equivalent circuit (EC), proposed for covered metal surfaces in solutions, can be satis-factorily applied. The values of the EC elements obtained by curve fitting to experimental results show the influence of the thermal treatments and/or moisture concentration on the impedance characteristics of polymer films. The mechanism of (co)polymer film formation as well as the electrical and corrosion protection properties are discussed with regard to the experimental parameters and some characteristics of the films obtained.
