Effect of Hydrocarbon Chain Length on Arrangement of Chemically Adsorbed Monolayers

Abstract

FTIR spectra and contact angles were measured on some monolayers prepared from one of the silyl-type surfactants having a hydrocarbon chain, n-Alkyltrichlorosilane, by a chemical adsorption (CA) technique. Molecular arrangement in the monolayer made by the CA technique, the CA monolayer, was random or bulklike as long as the carbon number of the hydrocarbon chain was less than 8, and the CA molecules were arranged along the surface of the substrate when the number became 8 and over. © 1992, American Chemical Society.
