Title: Preparation and evaluation of two-dimensional polymer films by chemical modification of an alkanethiol self-assembled monolayer for protection of copper against corrosion

Abstract

Chemical modification of an 11-mercapto-1-undecanol (MUO) self-assembled monolayer chemisorbed on the copper surface with alkyltrichlorosilanes (C{sub n}TCS) has improved the protective ability of the monolayers against corrosion of copper in aqueous and atmospheric environments. In this study, further improvements of the ability were investigated by modification of the MUO self-assembled layer adsorbed on copper with tetrachlorosilane (TCS) and 1,2-bis(trichlorosilyl)ethane (BTCSE) for constructing a two-dimensional polymer structure in the assembly layer on the surface. The TCS or BTCSE-modified MUO monolayer was further treated with coupling agents like octyldimethylchlorosilane, octamethyldichlorosilane, and octyltrichlorosilane. The modified monolayers were characterized by Fourier transform infrared reflection spectroscopy and contact angle measurements. Although the protective abilities of the modified layers against the cathodic reaction of copper corrosion in aerated 0.5 M Na{sub 2}SO{sub 4} were not necessarily increased remarkably from those of the C{sub n}TCS-modified MUO monolayers, network structures arising from two-dimensional polymerization with lateral siloxane linkages between molecules adsorbed on copper resulted in enhancement of the protective ability against the anodic process.
