Superhydrophobic Perpendicular Nanopin Film by the Bottom-Up Process
TLDR
A water contact angle of about 178 degrees can be achieved using a lauric acid-coated film with an original contact angles of 75 degrees based on an ideal fractal structure for the superhydrophobic surface which is fabricated by the nanosize pin with 6.5 nm diameter.Abstract:
We first fabricated the superhydrophobic film with a water contact angle of 178° based on a perpendicular nanopin fractal structure by a bottom-up process. Until now, only materials with an original water contact angle larger than 90°, which is classified as hydrophobicity, could be used to fabricate the superhydrophobic film (>170°) according to the possible fractal structure by a top-down process. Now, in this work, a water contact angle of about 178° can be achieved using a lauric acid-coated film with an original contact angle of 75°, which is classified as hydrophilicity, based on an ideal fractal structure for the superhydrophobic surface which is fabricated by the nanosize pin with 6.5 nm diameter.read more

Superhydrophobic surfaces: from structural control to functional application
TL;DR: A superhydrophobic surface is a surface with a water contact angle close to or higher than 150° as discussed by the authors, and it is the combination of surface roughness and low-surface-energy modification that leads to super-hydrophobicity.

Effects of Surface Structure on the Hydrophobicity and Sliding Behavior of Water Droplets
TL;DR: In this article, the sliding behavior of water droplets over pillarlike and groove structures was investigated and a proper design of the surface with respect to shape and extent of the three-phase line is more effective than the increase of contact angles merely by decreasing the solid−water contact area.
