Abstract

The interaction of water with pre-heat treated silylated aerosil samples was investigated by adsorption of water and by contact angle measurements at 293 K. Type II adsorption isotherms were obtained. The resulting BET specific surface areas were found to depend on pre-treatment. Contact angles were measured by the captive bubble method at the three phase contact line in water, on glass slides similarly modified. Silylation was found to decrease water adsorption on aerosil and increase the contact angles on the glass slides to extents that depend on the silane used as well as the concentration of residual silanols and on concentration and size of surface silyl groups.
