| titleOfInvention | Porous nano-ceramic constructed by hydroxyapatite nanorods or sheets and preparation method thereof |
| abstract | The invention relates to porous nano-ceramic constructed by hydroxyapatite nanorods or sheets and a preparation method thereof, belonging to the technical field of biological materials. The method comprises the following steps: performing nanocrystallization on porous ceramic containing tricalcium phosphate by using a hydrothermal method, namely mixing an ethylenediaminetetraacetic acid water solution with the concentration of 0-0.5mol/L and a water solution of Ca(NO3)2.4H2O and (NH4)2HPO4 with the concentration of 0-0.5mol/L and the molar ratio of Ca: P of 1.67 to get a mixed water solution; regulating the pH value by using hydrochloric acid and sodium hydroxide; and further adding the porous ceramic containing tricalcium phosphate and the mixed water solution into a hydrothermal reaction kettle for reaction, and controlling temperature and time to get the porous nano-ceramic constituted by the hydroxyapatite nanorods or nano-sheets. Compared with traditional calcium phosphate porous ceramic, the porous nano-ceramic constructed according to the invention has the advantages of higher biological activity and improved degradability; and the preparation method is simple, high in repeatability and capable of realizing large-scale production. |
