Abstract

Ultrathin (less than 5.4 nm), ordered (self-assembly), and highly interconnected (one- and two-dimensional polymers) protective films were prepared on a passivated iron electrode by chemical modification of a carboxylate self-assembled monolayer with alkyltriethoxysilanes. Prevention of passive film breakdown by coverage of the passivated electrode with the films was examined by anodic polarization measurements in a borate buffer containing 0.1 M Cl-. Complete protection of the passive film against breakdown was observed over the passive and transpassive regions.
