Modification of the metallic surface of silver by the formation of alkanethiol selfassembled monolayers with subsequent reaction with chlorosilanes

Abstract. This report describes effect of the preparation procedures on the quality of self-assembled monolayers (SAMs) on the silver surface for developing protective films against attack by atmospheric pollutants including oxidation. Various silver substrates covered with the 11-mercapto-1-undecanol (MUO) and chemically modified MUO with octyltrichlorosilane were analyzed by X-ray Photoelectron Spectroscopy (XPS). Difference in composition of monolayers from n-alkanethiols at Ag relative to the method used for cleaning the surface and other preparation details were observed. Contrarily to the assembly of high-quality alkanethiolate monolayers and its subsequent modification by chlorosilanes on gold surface preparation of SAMs on the surface of silver were more complex and the least reproducible. 1
