Abstract

We have used multiple-beam interferometry to study the temperature dependence of tert-butanol adsorption from vapor on mica, at an isolated surface and in a slit pore. The film thickness at one surface increases from 2 nm for 17-24 °C to >7 nm above the triple point T_tr (25.5 °C). Concomitantly, the surface separation at which the slit fills with liquid increases from 11 to 27 nm. These results show for the first time how a continuous triple-point wetting transition at one surface and suppression of the freezing transition in a slit pore affect capillary condensation near T_tr.
