Surface structure and wetting properties.

(a) SEM micrograph of PVDF random fiber mat. Inset shows the rough surface of individual fibers. (b) Water drop sticking to a random fiber mat. Inset shows same water drop when right side up. (c) Camera pictures showing fibers being pulled out of random fiber mat, along with the water drop. Inset shows the drop ultimately staying with fibers mat. (d) SEM micrograph showing the surface of half of the yarn. Random fiber mat under the yarn is visible in the background. (e) Top view of a water drop sitting on PVDF yarn that was arranged on PVDF random mesh. (f) Sequence of pictures showing water drop sliding on yarn when it is tilted. Scale bar is 1 mm, unless mentioned.
