What dynamic contact angle measurements can tell you?

Wettability of a surface isn't fully captured by a single static contact angle value. A given surface can show a range of static contact angles, and dynamic measurements — advancing and receding angles, and the hysteresis between them — reveal that range.

This session looks at what dynamic contact angle data can tell you about a surface, and how automated needle and tilting methods make it fast and easy to generate reliable results. We'll cover what contact angle hysteresis and roll-off angle reveal about surface quality and homogeneity, and how dynamic measurements help characterize wettability for applications ranging from coatings, cleaning validation, and textiles to smart and superhydrophobic/-oleophobic surfaces.
