Abstract

Copper surfaces modified by hydroxamic acid amphiphilies were investigated in NaCl/Na2SO4 solution by surface visualization and electrochemical methods. Results of the atomic force microscopy and the polarization measurements show that the anticorrosion activity increases by increasing hydrophobicity of the molecules (i.e. with increasing number of carbon atoms in the alkyl side chain) and by increasing layer number in the LB film. The rate of pitting and general corrosions is lower in the presence of LB and SAM molecular films than without them. The efficiency of the same amphiphile in LB and SAM layers are different. The self-organization of the alkyl hydroxamic acid molecules can better control and diminish the corrosion processes of the copper than the LB film.
