Synthesis of organized hydroxyapatite (HA) using triton X-100

In this article, highly organized HA nanostructure was developed using a nonionic surfactant p-(1,1,3,3-tetramethylbutyl) phenoxypoly(oxyethylene) glycol (triton X-100) as the template. The obtained well-organized architectural units were examined using transmission electron microscopy (TEM), SEM, XRD and FTIR. High-resolution transmission electron (HRTEM) revealed that HA nanorods were well assembled in order along the c-axis. FTIR results indicated the possible interactions between triton X-100 and HA. The mechanism of the assembly of well-oriented nanostructure was proposed. The composites containing nanosized hydroxyapatite with structural features close to that of human bone should be useful and important for the practical applications, especially in the development of biomimetic materials.
