Аннотация:Lyophobized silicas containing relatively small numbers of grafted perfluorohexyl (1.1 nm–2) and perfluorobutyl (1.7 nm–2) groups are studied by means of gas chromatography, adsorption under static conditions, and IR spectroscopy. The results are compared to those obtained by us previously for a series of samples with dense polyfluoroalkyl monolayers (≥2.0 nm–2). Effects related to the influence of the grafting density and the size of fluorinecontaining groups on the adsorption of polar compounds and the hydrophobicity
of the surface are discussed.
