  • Sol-gel process is advantageous in preparing hydrophobic and super hydrophobic coatings in terms of providing high purity products at low temperatures, being easy and simple, applying to the materials with various shapes, being applicable to large areas, among many different coating methods.
  • hydrophobic, super hydrophobic and hydrophilic surface characters generally have been studied under the main headings of “surface protective coatings” and “application studies”.

  • the self-cleaning coatings are generally classified under two categories as hydrophilic and hydrophobic (water-repellent). While dirt and impurities are carried with the distributed water on the glass in hydrophilic coatings, water beams clean the surface by rolling like a ball in the hydrophobic coatings. The complicated dirt accumulated on the surface of the appropriate metal oxide is decomposed in the hydrophilic coatings with the help of sunlight. While the contact angle of the hydrophilic surface with the water is ⁇ 90°, it is >90° in hydrophobic surfaces and > 150° in super hydrophobic surfaces. Since there are potential applications in many sectors (textile, automotive, optics, marine, aviation etc.) of the self-cleaning coatings, many products are commercialized.

Since the super hydrophobic surfaces are anti-icing, electro-wetting and oil repellent, there are intensive research studies in terms of these surfaces.
