Artificial membranes represent models of the behavior of their biological counterparts. The objectives of this study are the formation and study of a biocompatible environment that serves as a support and ensure stability in phospholipids membranes. In this work was formed and analyzed experimentally a system composed of DPPC / CH / TiN + TiO2 / Ti, where DPPC is the phospholipid previously studied [J. Chem. Phys. 141, 104201 (2014)], chitosan CH , which acts as hydrating matrix for the phospholipid and TiN + TiO2 is the biocompatible surface of titanium Ti. The substrate used was Ti, material widely used in biomedical applications, but requires biocompatible coatings to be used in critical areas like implants. Coatings of titanium nitride (TiN) besides having well known properties of hardness, increase the corrosion resistance and maintain the biocompatibility of titanium.
