Abstract

For the first time, the surface composite Cassie-Baxter wetting state is carefully investigated using ginkgo biloba as natural model. Investigations follow two directions: (a) low local solid contact areal fraction leading to high apparent contact angles; and (b) thick air plastron trapped at the contacting interface leading to stable dewetting state.
