Transparent Superhydrophobic silica coatings on glass by sol–gel method

Wettability properties of PTFE/ZnO nanorods thin film exhibiting UV-resilient superhydrophobicity

“…Thus, when the sliding angle is small, the droplet can readily move on the surface. Therefore, low SA (below 10) is suitable for superhydrophobic application as also reported by others [41].…”

Hydrophobic sol–gel coatings based on polydimethylsiloxane for self-cleaning applications

“…To achieve effective self-cleaning over a long period of service time, these coatings have to be mechanically durable with high resistance to wear and erosion. Sol-gel technology is the preferred route to produce such coatings [1][2][3][4][5][6][7][8][9] because the desired properties of the coatings can be easily adjusted through formulation, including hardness, surface roughness, transparency, and surface energy, etc. In order to achieve superhydrophobic surfaces similar to that of the lotus leaf, two factors, viz.…”

Construction of mechanically durable superhydrophobic surfaces by thermal spray deposition and further surface modification

“…The construction of the surfaces by the emerging routes usually involves creating rough surface structures in the first place [10], followed by further modification with low surface energy materials such as fluorocarbons, fluoroalkyl-silane and hydrophobic silica [11][12][13]. Many processing techniques for example lithography patterning [14], layer-by-layer deposition [15], anodic oxidation [16], electrodeposition [17], sol-gel [18], mold fabrication-hot embossing process [19], electrospinning and chemical vapor deposition [20] have been attempted for fabricating hydrophobic surfaces. Regardless of the success of the abovementioned methods, large-scale fabrication of the surfaces with sufficient mechanical strength yet remains elusive.…”
