摘要：The hydroxyapatite (HAP) assembled microsphere chains/silver (Ag) nanocomposites were prepared by a facile in situ preparation method under hydrothermal condition. The crystal structure of products was characterized by X-ray diffraction (XRD) and the morphologies of products were investigated by transmission electron microscopy (TEM). The nanocomposites own large surface area and can hydrogen-bond to other substances by the hydroxyl group on the surface. The nanocomposites have good structural stability under the electrostatic effect of the silver nanoparticles and strong adsorbability of the HAP microsphere chains. The two substances combine to form special nanocomposite spheres. Specially, the HAP/Ag nanocomposites have high inhibitory activity and can be applied in the environment and medicine fields. The nanocomposite structures can save the consumption of Ag materials.
