The stability of superhydrophobic surfaces tested by high speed current scouring

Template-assisted encapsulation of fluorinated silanes in silica films for sustained hydrophobic–oleophobic functionality

“…Some methods employed by other researchers to combat this inherent difficulty include using textured surfaces to create mountains that protect functionalized valley areas from abrasive wear [19,22,23]. Nonetheless, surface alignment and stratification are inevitable and abrasive wear still has a large impact on surface functionality, eventually destroying the coating functionality by destruction or removal of the functional monolayer.…”

Assessing durability of superhydrophobic surfaces

“…Cui et al 41 prepared SHS with multiscale structures on paint films and tested its durability to the high speed scouring test and in neutral and basic aqueous solutions and in some common organic solvents. Cui et al 42 also studied the stability of four SHS by high-speed current scouring method. Zimmermann et al 43 studied the long-term environmental durability of a superhydrophobic silicone nanofilament coating with natural and artificial weathering tests.…”

A facile dip-coating process for preparing highly durable superhydrophobic surface with multi-scale structures on paint films

“…During the first 5 min of the test, the contact angle had an obvious decrease, reduced about 12°. It might be resulted from the loose particles being washed off the surface by the current, which generated a slightly reduced roughness of the surface [19]. Then the contact angle only showed a very little decrease as the scouring time increased, with the value remained at about 140°a t last, indicating a good durability of the superhydrophobic property against the water scouring.…”

“…This property is related to the special multi-scale nano/microsurface structures and this correlation is widely known as the lotus effect [6,[11][12][13]. In recent years, many technologies including electrochemical deposition [14][15][16], chemical [17][18][19][20][21][22] and plasma etching [23][24][25], electrospinning [26][27][28], and lithograph [29,30] are utilized to fabricate superhydrophobic surface by mimicking the lotus surface structure.…”

“…For example, many superhydrophobic surface are directly built up on metal surfaces [16][17][18][19][20][21], which are not stable in the conditions for many of above mentioned applications because these condition are usually corrosive to metal and can easily destroy the superhydrophobic structures. Therefore, for many of these applications, to create superhydrophobic surfaces on paint surfaces will be more promising than on the metal surface.…”
