Abstract

The present research effort consists in the development of phosphonic acid grafted nanosized hydroxyapatite (n-HAp) through a straightforward chemical methodology. Fourier transform infrared absorption spectroscopy (FTIR) and electron diffraction X-ray (EDX) studies show the stoichiometric creation of HAp particles. The existence of phosphonic acid on the hydroxyapatite particle surface was investigated through FTIR study also. Transmission electron microscopy (TEM) analysis divulges needle like acicular crystals of HAp particles with inexact size of 25-33 nm in diameter by 70-85 nm in length. The prepared hydroxyapatite material may be used in building a biocomposite with high interfacial bonding.
