Table 1 Average values with standard deviations of the apparent advancing (θa) and receding (θr) contact angles as well as the roll-off angles (RA) for 10 μL drops of water, ethylene glycol and hexadecane on the superamphiphobic surface, measured with goniometry.
Liquid | θa (°) | θr (°) | RA (°) |
|---|---|---|---|
Water | 161 ± 1 | 159 ± 1 | < 1 |
Ethylene glycol | 161 ± 1 | 151 ± 2 | 2 ± 1 |
Hexadecane | 160 ± 2 | 150 ± 5 | 2 ± 1 |
