Fig. 5. Water collection effect for different surfaces after 5 hours test. In this test, the environment temperature was 22 ± 3 °C and the fog flow speed was ∼0.9 m s−1. (a) The weight of collected water for different surfaces varies over time. (b) Water collection rate and retained water for different surfaces. Compared with the Nano and the Untreated sample, water collection rate of the BSC is improved by ∼67% and ∼81%, respectively.
