| contents | Interfacial analysis of chitosan/bone: cortical and cancellous bone matrices C.V. Paz López S.R. Vasquez-Garcia N. Flores-Ramirez Física, Astronomía y Matemáticas Thermal stability and phase separation of a film on a substrate can be controlled at the interface level by changing the compatibility between both components, which is based on molecular interactions. Thus, in this study chitosan was used as a coating age nt due to its superior film - forming properties and multiple molecular interactions with bone. In particular, two types of bone substrates were considered to study the bio - adhesion phenomena: cancellous and cortical bones. Firstly, chitosan/bone samples wer e prepared by controllable dip - coating method under fixed conditions, and subsequently an experimental investigation was utilized to analyze the interfacial compatibility and interaction between chitosan with the two bone substrates. As a result, Fourier t ransform infrared spectroscopy (FTIR) data revealed a strong interaction between the chitosan molecules and bones. Meanwhile, by scanning electron microscope (SEM) and microhardness analysis a moderate interfacial compatibility was exhibited. Furthermore, analyses by X - ray diffraction were used to identify the spatial arrangement of chitosan structure on bone, which was increased as a result of an increase in acidity of chitosan solution. 2016 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94251122002 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
