Gelatin can be obtained by thermal denaturation or physical and chemical degradation of collagen, the main protein of bone tissue. Since gelatin is a biocompatible polymer, it is completely resorbable in vivo. Hence, gelatin can be considered as a strong candidate for the use of biomaterial. The purpose of this study was to improve the biocompatibility of the ceramic film by using natural polymer, gelatin. We prepared composite films consist of calcium phosphate (CaP) and gelatin. The film characteristics such as surface morphology and roughness were analyzed using SEM and AFM. The prepared CaP-gelatin film showed highly porous and 3D structure. The chemical properties of the calcium phosphate-gelatin composite film were characterized with XPS and FT-IR. In addition, we studied the effect of the gelatin concentration on the formation of calcium phosphate-gelatin composite film. We observed that the composite films were formed at low gelatin concentration. Interestingly, the film formed at very low concentration appeared to be compact and plate-like. |
