ADSORPTION AND INTERPHASE INTERACTIONS IN METAL SILANE AND METAL SILANE POLYMER SYSTEMS

Adsorption of ethoxysilanes from their vapors and aqueous solutions by aluminum is studied by the method of piezoelectric quartz crystal mic roweighing. The ''landing places'' are calculated for individual molec ules in an irreversibly sorbed monolayer of them. The role of adsorbed water in the chemisorption of silane is established. Monolayer silici ding halves oxide film growth rate and corrosion of aluminum in water. Only chemisorbed aminosilane molecules promote adhesion in an aluminu m-epoxy resin adhesive point, and there is sufficient filling by a 0.3 monolayer of them. In order to improve water-resistance multilayer fi lling of the surface and formation of a ''transition zone'' of interpe netrating networks chemically bonded with the metal are necessary.
