Abstract

A self-assembled monolayer (SAM) of p-hydroxymethylbenzene moiety adsorbed on iron by the formation of a covalent bond between iron and carbon atoms was prepared by electrolytic reduction of diazonium ion. Ultrathin polymer films of the SAM were prepared on the iron surface by chemical modification with alkylethoxysilanes. The protective abilities of the films against iron corrosion were examined by polarization measurements in an aerated 0.5 M NaCl solution. High protective performances of the films were obtained after immersion in the solution for many hours due to the formation of a strong adsorption bond.
