| 摘 要： | The study on the effect of surface topography on hy- drophobicity involves solid-liquid-gas contact line ef- fect and solid-liquid interphase effect. The former is chiefly related to the wettability of the solid surface, while the latter is mainly concerned with the solid-liquid interface resistance during the process of relative movement. The hydrophobicity or wettability is one of the main characteristics of solid surface, determined by both the chemical components and the microstructures of…

| Abstract: | Ultra hydrophobic surfaces take on better hydrophobicity and exhibit a water contact angle larger than 150°. In this paper
the ultra hydrophobicity is analyzed and common fabrication methods are summarized in detail. The applications of micro topography
in both the fabrication of hydrophobic surface and the experiments of drag reduction are addressed. Finally, the development
trend and foreground of ultra hydrophobic surface are discussed. |
