چکیده

In this work needle like hydroxy apatite were synthesized in a reverse microemulsion droplets of water in cyclohexane, separated by a cationic surfactant and co-surfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. Characterization of the as formed HAp nanoparticles at the room temperature were carried out by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the samples were investigated using scaning and transmission electron microscopy (SEM and TEM). The results obtained confirm incorperation of PAA as a template in controlling of the size and morphology of HAp nanoparticles into the individual microemulsion droplets.
