Hydrophobic coatings based on SiO2

Abstract

The method of conversion, properties and usage of hydrophobic coatings on the bases of silicon dioxide is presented in the article. These layers are formed by use the silanes which are not react with water. What is more, these layers could provide not only great resistance to the effect of water molecules, but also better resistance to the effect of abrasive action and hardness as well as keeping the top stair of the transparency. Uncomplicated methods such as zol-zel are used to settling these layers. There are methods of putting on the various surfaces, without necessity of usage specific and sophisticated technological solutions. As a transparent and simple to keep in the cleanness surfaces these layers found application in various field such as sport, motorization, building industry, optical system whether in our houses.

Emerging Multimodel Zirconia Nanosystems for High‐Performance Biomedical Applications

“…This processing technique is primarily associated with the preparation of a sol, followed by gelation and solvent removal. [ 40 ] In this method, the solution (sol) gradually progresses toward constructing a gelatinous network comprising both liquid and solid phases, which further transforms into a solid crystalline or amorphous structure. The translation of the sol into a gel form primarily depends on the dehydrated colloidal solution generated from the material hydroxide particles.…”

“…Generally, the alkoxides of different elements are used as starting precursors in the sol–gel method. [ 40 ] The initial step involves the hydrolysis of precursors (metal–organic compounds) into oxohydroxide compounds, followed by the condensation step resulting in a metal hydroxide network. Finally, the polymerization step provides a porous gel.…”

“…It executes multiple advantages such as fewer instrumentation costs, generation of nanostructures with stable and high surface area, no release of toxic wastes, and the ability to attain color layers. [ 40 ]…”
