Problems solved by technology

However, it has been reported that the synthesis method of hydroxyapatite material is relatively complicated, and it is difficult to meet the actual application requirements of mass production.
Up to now, there is no method in the field to prepare hydroxyapatite micro-nano materials with various shapes such as linear, rod, spherical and tubular in one step only by changing the phosphorus source under the same synthesis system

Abstract

The invention relates to a method for regulating the morphology of a hydroxyapatite micro-nanomaterial by using a phosphorus source. The method comprises the following steps: mixing anhydrous ethanoland palmitic acid, adding an aqueous solution of a soluble calcium salt and an aqueous solution of a strong alkali, and performing magnetic stirring until uniformity in order to prepare a calcium palmitate precursor; adding an aqueous solution of various phosphorus sources such as a phosphate dodecahydrate, a trimetaphosphate, a tripolyphosphate, and a hexametaphosphate to obtain a reaction solution, adding the reaction solution into a hydrothermal kettle, and carrying out a solvothermal reaction; and washing and drying the obtained reaction product to obtain the hydroxyapatite micro-nanomaterial with various morphologies such as a ultra-long nanowire, a nano-short rod, a petal-like microsphere and a micro-tube. The method can be used to conveniently and quickly obtain the hydroxyapatite micro-nanostructure with the controlled morphology, and the hydroxyapatite micro-nanomaterial can be applied to many fields of bone tissue repairing, suture, hemostatic dressings, adsorption bioactivesubstances, drug loading and release, bone filling and cell / drug loaded implants according to actual needs.
