Table 2. Wettability and Anti-icing Parameters of Untreated and Coated CFR Panels: CA, CAH, and Freezing Timea.
sample | CA (deg) | CAH (deg) | freezing time (s) |
---|---|---|---|
panel | 62 ± 3 | 35 ± 5 | |
EPO | 84 ± 2 | 55 ± 3 | 54 ± 2 |
EH_HDTMS | 96 ± 3 | 43 ± 2 | 78 ± 3 |
EH_PFOTES | 115 ± 3 | 33 ± 4 | 113 ± 5 |
CAH was not measured for the pristine panel as the droplet could not slide down.
