Figure 8

Synthesis of the composite superhydrophobic coating. (a) Schematic of the fabrication of the superhydrophobic coating and the possible bonding structure in the composite coating. (b) FTIR spectra of the composite coating. (c) SEM image of the composite coating on a glass slide. (d) AFM height image of the superhydrophobic surface. Inset: AFM section images of the positions marked by the line. (e) Time-resolved images of a 9.0 μL water droplet spreading quickly on the composite coating within 162 ms (tilting angle < 3°). (f) The contact, deformation, and departure processes of a water droplet on the composite coating. (g) The water contact angles and sliding angles of the composite coating on various substrates [142].
