The morphology, nanostructures, and crystallinity of hydroxyapatite (HA) materials have significant effects on their physicochemical properties and biomedical applications. However, the controllable synthesis of HA nanomaterials with various size and morphology using the same synthesis system, though desirable, has remained a challenge. In this work, we successfully synthesized HA nanomaterials with different morphologies via a one-step solvothermal route in the same reaction system. By using (NaPO3)3, Na3PO4·12H2O and NaH2PO4·2H2O as phosphorus sources, the growth of HA crystals was regulated, resulting in the transformation of HA nanomaterials morphology from nanorods to nanowires. Different concentrations of PO43− and OH− ions in the reaction environments regulated by different phosphates lead to different nanostructures of HA crystals. Our work provides an instructive way to controllably fabricate HA nanomaterials with various morphologies and will widen the biomedical applications of HA materials.
