A superhydrophobic surface fabricated by an electrostatic process.

We describe the fabrication of a biomimically designed superhydrophobic poly(ε-caprolactone) surface, which was obtained using a modified electrostatic process. The fabricated surface exhibits a micron-sized pyramid structure consisting of accumulated droplets and nanofibres. By using this simple one-step process, we can achieve a superhydrophobic surface having both a high water contact angle and low threshold sliding angle, similar to that of the superhydrophobic plant leaf.
