    • The receding contact angle for clean capillaries flushed with room temperature water is 37° (see Figure 8b) and remains fairly constant for a variety of treatment conditions. In contrast, the advancing angle varies considerably with the treatment. When the contact line is situated with the vapor side in a region never prewet by liquid, the advancing angle was observed to be as high as 50° (see Figure 8a, an indication of a very low surface silanol coverage. But when the vapor side is in a previously wetted region, where surface silanol coverage could increase due to hydrolysis, the advancing angle approached the value of the receding angle (see Figure 8c, In a hot water flushed clean capillary, on the other hand, the advancing angle was equal to the receding angle ∼36°, regardless of me history of the vapor phase capillary section at which the measurements were made.

    • The receding contact angle for clean capillaries flushed with room temperature water is 37° (see Figure 8b) and remains fairly constant for a variety of treatment conditions.

In a hot water flushed clean capillary, on the other hand, the advancing angle was equal to the receding angle (∼36°), regardless of me history of the vapor phase capillary section at which the measurements were made. In this case, the higher temperature appears to cause rapid hydrolysis and water adsorption ahead of the contact line, which results in equal advancing and receding angles. These results show the importance of the presence or absence of a leading edge water film at the silica surface contiguous with the contact line. (See Kalliadasis S.; Chang H. C. Phys.
