Table 2. Summary of Water Contact Angles, Sliding Angles, Contact Angle Hysteresis, and Root-Mean-Square Heights for the 0.5PDMS/SiO2/0.5(SA+PA)/40 and 0.5PDMS/SiO2/0.5FAS/40 Films (with and without FAS C8, respectively).
| film | FAS C8/fatty acid used | deposition time (min) | water contact angle (deg) | sliding angle (deg) | contact angle hysteresis (deg) | Sq (μm) |
|---|---|---|---|---|---|---|
| 0.5PDMS/SiO2/0.5(SA+PA)/40 | 50:50 stearic acid/palmitic acid mixture | 40 | 163 ± 1 | 4 ± 1 | 14 ± 4 | 0.60 |
| 0.5PDMS/SiO2/0.5FAS/40 | FAS C8 | 40 | 161 ± 2 | 4 ± 1 | 20 ± 9 | 0.66 |
