Figure 3

Relationships between the pillar height (h) and water contact angle (CA) on PTFE(h,m)/Q (m = (A) 100, (B) 200, (C) 400, and (D) 635). Dotted line shows the calculated value of CA by using Wenzel equation (open triangle) and Cassie-Baxter equation (open square). Inset of this figure shows the photographic images of water droplet on each sample.
