Preparation of UV curable organic/inorganic hybrid coatings-a review

The ultraviolet (UV) curable organic/inorganic hybrid coating is a kind of environment friendly paint products with rapid development in recent decade. It combines UV curing and nanofabrication technique. Due to its distinct advantages of zero volatile organic compounds emission, high curing rate at room temperature, and excellent performance, UV curable organic/inorganic hybrid coating has been considered as a green product with extensive application prospect. In this review, we focus on the preparation methods of UV curable organic/inorganic hybrid coatings including blending method, sol gel process, intercalation and in-situ reaction. All the preparation methods have the same core concept of incorporation between the organic and inorganic composition in molecular level in order to take full advantages of both organic and inorganic composition. The properties of hybrid coatings can be enhanced by the inorganic incorporation into the organic matrix, such as abrasive resistance, heat resistance, corrosion resistance, chemical stability and etc. The research progress on different inorganic particles applied in UV curable organic/inorganic hybrid coatings is also summarized.
