Facile preparation of durable superhydrophobic coating with self-cleaning property

Water droplet on inclined dusty hydrophobic surface: influence of droplet volume on environmental dust particles removal

“…The fabrication of hydrophobic surfaces towards creating self-cleaning effects on surfaces was one focus of interest. [8][9][10][11][12][13][14][15][16][17][18][19][20] A hydrophobic organic layer on a surface could be formed via chemical etching, followed by the deposition of oxide nanoparticles. 8 The resulting wetting state of the coating surface could be further increased by depositing a thin layer of organic molecules on the coating surface.…”

“…The hydrophobic coating produced from a mixture of nano-sized TiO 2 , attapulgite (epoxy resin), and polydimethylsiloxane was found to be durable, retaining its self-cleaning ability under wearing environments. 15 On the other hand, the hydrothermal process could be used in the fabrication of hierarchical CuO spheres on polyimide substrates, which was reported to involve a simple process and could be used effectively for the self-cleaning of organic and inorganic particulates from surfaces. 16 Sol-gel processing also created a hydrophobic wetting state at the surface, which could be used for self-cleaning applications; 17 however, the durability of the resulting sol-gel coating in self-cleaning applications was not promising.…”

Facile Fabrication of Durable Superhydrophobic Films from Carbon Nanotube/Main-Chain Type Polybenzoxazine Composites

“…However, the organic coatings usually deteriorate upon UV exposure, decreasing the self-cleaning properties of superhydrophobic films. Recently, some researchers have developed several UV-durable superhydrophobic materials to address this limitation [22,23,24,25]. Wong and coworkers synthesized durable coatings with superhydrophobicity through template-free micro-nano texturing of interpenetrated polymer networks [22].…”

Investigation of the Effects of Component Ratios on the Properties of Superhydrophobic Polyurethane/Fluorinated Acrylic Co-Polymer/SiO2 Nanocomposite Coatings

“…However, the water contact angle of these polymers is generally less than 120 • on a homogeneous flat surfaces. The incorporation of inorganic nanoparticles, such as SiO 2 [32,33], TiO 2 [34,35] and ZnO [36,37], can increase the surface roughness of the hydrophobic coatings, therefore, their contact angles, based on the Wenzel and Cassie-Baxter models, which show excellent water repellence and superhydrophobicity. For example, Satapathy et al [38] prepared linear low density polyethylene (LLDPE)/SiO 2 superhydrophobic nanocomposite coatings by dip-coating technique.…”
