Nowadays, the use of glass facades has attracted attention for many reasons, such as the beauty and low energy consumption and, of course, the reflection of sunlight in hot cities. Due to the height of the buildings, the need to clean the facade of the building during maintenance and repairs is important. There is also a need to clean the glass surface in applications such as solar cells made of glass plates that absorb sunlight and convert it to electricity. In addition, cleaning the surface of the car's glass is important to improve driving conditions. Washing with water and detergent is a common but costly way of cleaning of various types of glass surfaces. A good alternative to these methods is applying hydrophobic coatings. Applying of these coatings causes water particles to not adhere to the surface and also to remove dirt or particles from the surface by water droplets. The use of colloidal coatings containing nanoparticles creates a very high contact angle (usually over 100 degrees) as well as low surface energy and reduces the capillary property between the water droplets and the surface and creates a spherical shape in the droplets which results in easy moving on the surface. As a result, stains on the surface are prevented and no need for continuous washing and use of acidic detergents, as well as preventing blurring of glassy surfaces.
