Fabrication of super-hydrophobic film with dual-size roughness by silica sphere assembly

An introduction to superhydrophobicity

“…More organised structures can be formed if the particles are aggregated under control and multiple particle sizes can be used to improve the effect. Several products are on the market that consist of particles suspended in a dilute matrix to produce a superhydrophobic paint [63,64,65].…”

Superhydrophobicity of cotton fabrics treated with silica nanoparticles and water-repellent agent

“…As silica is not hydrophobic due to abundant hydroxyl groups on its surface, it is needed to treat the silica surface with a hydrophobic material. As mentioned above, there have been many reports on using alkylated or fluorinated silanes for hydrophobication of silica [15][16][17][18][19][20][21][22][23][24]. However, the hydrophobic silane compounds have been limited in practical applications due to their high cost.…”

“…There are several kinds of inorganic nano-size particles such as SiO 2 , TiO 2 , and ZnO [12][13][14]. Surface-modifying chemicals of fluorinated silanes [15][16][17][18][19] or alkylated silanes [20][21][22][23][24] have been used to transform the hydrophilic surface of the particles into hydrophobic ones.…”

Insights into the heterogeneous distribution of SERS effect in plasmonic hot spots between Au@SiO2monolayer film and gold single crystal plates

“…In general, the surface properties of NPs with thicker silica shells are close to those of pure silica spheres which allow to form monolayer array structures. [36][37][38] The continuous silica shells blocked the pinhole effect signicantly (see the ESI, Fig. S4 †).…”
