Most surface coatings have properties such as mechanical, physical, thermal, chemical, and optical properties for different applications. For some applications such as food and pharmaceutical packaging, encapsulation of the electrochemical cells, such as solar cells and light emitting diodes, in addition to these general properties, impermeability to moisture is also important. These coatings are designed for such applications based on the structure of the high crosslinking density, proper polarity (hydrophilic / hydrophobic) and the degree of crystallinity. These coatings can be prepared from organic polymer, inorganic or hybrid (organic – inorganic) materials. This coverage can be a single layer or multiple layer through several processes deposited on polymeric substrates. Hybrid coatings are intended for such applications, because of the structure of organic and inorganic materials can combine the properties and features of organic materials such as flexibility, toughness, processing and properties of inorganic material such as elasticity, surface energy and resistance against permeation. In this paper a review on the properties of these hybrids have been discussed.
