Composite materials have showing potential applications in biomaterials. Among the composite materials, HAp/ polymer possesses significant advantages of high mechanical reliability and excellent biocompatibility for applications involving artificial bones and teeth. The aim of this study was to develop nanocomposites of hydroxyapatite and polyéthylène glycol (HAp/ PEG 1000), also the study of the adsorption of the bisphenol A (PBA) with composite synthesized. The structure were synthesized and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and field emission-scanning electron microscopy (FE-SEM). The results revealed that the size of HAp nanoparticles decrease with increase in PEG concentration in the composite. SEM image shows particles with an average diameter of 50 to 60 nm. Furthermore, At elevated temperatures the molecules of polyethylene glycol is evaporated and leads to the formation of platelet HAP.
