3.2. Static and dynamic wetting properties of RB-like coatings
The solution A was drop casted on the glass substrate which showed water contact angle higher than
1551 after drying at room temperature. The silica particles originated from
17FTMS contains long chain fluorocarbon groups on the surface, which are strongly hydrophobic in
nature. Due to the hierarchical surface morphology of the drop casted film, the water drops achieve
contact angles in the superhydropho- bic state.
