摘要

Effect of droplet size on wetting behavior on laser textured SiC surface was studied in this work. The microsquare-convex surface was processed on smooth surface with intrisinc contact angle 101 degrees. Then contact angles were measured on both smooth and textured surface by sessile drop method using deionized water with different droplet volume. It was found that there was significant droplet size effect on wetting behaviors for the textured SiC surface. Contact angles on smooth surface kept stable for different water droplet volume with a variation amplitude 13 degrees. However, contact angles increased significantly from 42.25 to 131.25 degrees with increasing droplet volume from 0.001 mu L, to 1 mu L, then remained unchanged when the droplet volume exceeds 1 mu L. The correlation analysis shows that contact angles increase with the increasing ratio of base diameter and groove width, then keep stable when the ratio exceeds 25, which explains the wetting behavior for different droplet volume.
