Abstract

The invention discloses a method for preparing a hydroxyapatite nano rod by using an egg white template, and belongs to the technical field of biological ceramic materials. The method comprises the following steps: taking calcium chloride (CaCl2) as calcium salt, diammonium hydrogen phosphate ((NH4)2HPO4) as phosphate and ethanol amine (C2H7NO) as a reaction chelating agent, carrying out rotary evaporation reaction under a high-concentration alkaline condition to obtain an HA precursor solution, washing with water and alcohol, carrying out vacuum drying to obtain HA precursor powder, uniformly mixing and stirring the HA precursor powder and whipped egg white, placing the mixture into a drying oven, drying, and successfully preparing the hydroxyapatite nano rod through high-temperature calcination. In the synthesis process, common inorganic salts and simple reagents are mainly used, so that the method is low in cost, simple and feasible, good in repeatability, high in synthesis performance, good in stability, suitable for large-scale production and capable of promoting the commercialization process of biological ceramic materials.

Description

technical field [0001] The invention relates to the technical field of bioceramic materials, in particular to a method for preparing hydroxyapatite nanorods using egg white templates. Background technique [0002] Bioceramic is a ceramic material that can be directly or indirectly used in the human body, and has good biocompatibility, tissue affinity and chemical stability. Hydroxyapatite is the main inorganic component of animal bones and teeth, and is the most common and widely used calcium phosphate bioceramic. Moreover, in addition, HA is also of great interest in other non-biological fields, such as catalysis and water treatment. Research scholars have conducted a lot of exploration on its preparation technology to make it meet the application requirements. So far, a variety of preparation methods have been perfected, mainly including hydrothermal method, precipitation method, solid phase reaction method and so on. Currently, the hydrothermal method is the mainstream...
