POSS Incorporated Organic-Inorganic Polyurethane Hybrid Coatings with High Biocompatibility

This paper considers the biocompatibility of POSS/polyurethane hybrid coatings. Two types of POSS were added into polyurethane; one covalently bonded with the matrix while the other one was physically blended. The physically added POSS could migrate into the surface and accumulated at the interface of air and coating film. This converted a non biocompatible material to a highly biocompatible surface. Cell viability and atomic force microscopy were conducted to reveal this phenomenon
