Abstract
The data also suggests that contact angle does not always correlate with sliding angle but surface roughness does correlate with sliding angle. The three roughest surfaces used in this experiment caused water drops to adhere to them so strongly that drops would not slide off of the surface, even when the surface was elevated to a completely vertical position. Lastly, drops placed on surfaces with large machined features (0.01”) were observed transitioning from the Cassie-Baxter state to the Wenzel state, suggesting that these features are too large or rough to allow the drops to remain in the Cassie-Baxter state for extended periods of time.
