Název v původním jazyce

Self-assembled monolayers of vinyltriethoxysilane and vinyltrichlorosilane

Popis výsledku v původním jazyce

Although a molecular monolayer is only a few nanometers thick, it can completely change the chemical and physical properties of a surface. Molecular monolayers can be readily prepared using chemisorptions on a variety of surfaces. The self-assembled monolayers (SAMs) are highly ordered two-dimensional structures that form spontaneously by the immersion of an appropriate substrate into a solution of an active surfactant in an organic solvent. The most common adsorbate/substrate combinations are alkylsilanes on oxide surfaces. Our study is aimed at SAM deposition using vinyltriethoxysilane (VTES) or vinyltrichlorosilane (VTCS) molecules chemisorbed on silicon oxide surfaces. The kinetics of formation of VTES or VTCS monolayers on planar glass substrate or silicon wafer with native silicon dioxide layer was characterized by contact angle measurements. The surface free energy and its components were evaluated using the Owens-Wendt-Kaelble geometric mean method and the Wu harmonic mean meth
