Self-cleaning coatings

Photocatalytic Ti02 particles cannot be incorporated or deposited on the organic coating, as they oxidize the polymer. Recent developments have revealed the use of Ti02 particles in combination with organic resins [55-57].

Titanium dioxide (Ti02) is a typical n-type semiconductor that has been widely used in industry due to its unique and various properties such as its antibacterial properties, its stability, its super hydrophilic behavior under radiation, and its photocatalytic properties [55]. This material is found in applications such as photovoltaic cells with dye-sensitized solar cells (DSSCs), sensors, self-cleaning coatings, painting, and air and water depollution (heterogeneous catalysis).

Zhang et al [105] published a review on superhydrophobic surfaces considering several aspects to develop self-cleaning coatings with antireflection (AR) properties. They reported the preparation of multilayer stacks with an inner... 

Superhydrophobic materials have surfaces that are extremely difficult to wet, with water contact angles in excess of 150° or even greater, see Fig. 20.6 shows that surfaces with ultrahydrophobicity have aroused much interest with their potential applications in self-cleaning coatings, microfluidics, and biocompatible materials and so on. Many physical-chemical processes, such as adsorption, lubrication, adhesion, dispersion, friction, etc., are closely related to the wettability of materials surfaces [52, 53]. Examples of hydrophobic molecules include alkanes, oils, fats, wax, and greasy and organic substances with C, N, O, or F as the key constituent element.
