Abstract

We made nanopillars with intervals of several tens of nanometers and diameter, and examined wettability. When the interval is narrow, the capillary phenomenon can be suppressed and hydrophobicity is realized. On the other hand, when the interval was widened, the wettability decreased due to the capillary phenomenon. As a result, it was found that the Cassie-Baxter model with filling factor gives a hydrophobic effect as the wetting property becomes narrower.
