Abstract: Polyhedral oligomeric silsesquioxane(POSS), as a type of nano-sized organic-inorganic hybrid material, has drawn much attention in coatings industry within the last decade. This article introduces the structure, characteristics and preparation of POSS,meanwhile, describes the development of Poss-modified polymer and its application in coatings. It is indicated that POSS modification can significantly improve the thermal stability physical properties and fire retardant performance, etc. of the coatings. In addition, the future rends of the Poss-modified coatings are given.

Key words: polyhedral oligomeric silsesquioxane, hybrid material, organic-inorganic hy-brid functional coating
