Abstract
According to an example embodiment, a patterned surface includes a micro-structural surface with a micro or nano pattern on a substrate, wherein the micro-structural surface has superhydrophobic regions and superhydrophilic regions.
Claims24
A patterned surface, comprising:
- a micro-structural surface formed on a substrate, the micro-structural surface having at least one of a micro pattern and a nano pattern, and the micro-structural surface having superhydrophobic regions having a water contact angle (WCA) greater than 120 degrees and superhydrophilic regions having the WCA less than 50 degrees.
A patterned surface, comprising:
- a micro-structural surface with a micro pattern on a substrate, the micro-structural surface including projection planes and groove planes;
- and each of the projection planes and the groove planes including at least one of a nano-patterned plane and a flat plane.
