Embodiment 1

[0024] First, dissolve 0.15 g of cetyltrimethylammonium bromide in 50 ml of distilled water, then add calcium nitrate tetrahydrate and sodium dihydrogen phosphate so that the molar ratio of the two is 1.1, and stir evenly. The reaction solution was sonicated with an ultrasonic cell disruptor. The ultrasonic frequency is 20kHz, the processing time is 20min, and the power is 800W. After the reaction, the reaction solution was cooled to room temperature and filtered. The product was washed several times with distilled water and ethanol, respectively. Finally, the product was dried in a drying oven at a temperature of 60° C. and a drying time of 24 hours.

[0025] The obtained product was characterized by X-ray diffractometer (XRD), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). Characterization results show that the obtained product is monetite nanosheets with a thickness of about 100 nm. The exposed crystal faces of the nanosh...

[0027] First, dissolve 0.20 g of bis-octyl dimethyl ammonium chloride in 50 ml of distilled water, then add calcium nitrate tetrahydrate and sodium dihydrogen phosphate so that the molar ratio of the two is 1.1, and stir evenly. The reaction solution was sonicated with an ultrasonic cell disruptor. The frequency of ultrasound is 20kHz, the processing time is 30min, and the power is 600W. After the reaction, the reaction solution was cooled to room temperature and filtered. The product was washed several times with distilled water and ethanol, respectively. Finally, the product was dried in a drying oven at a temperature of 60° C. and a drying time of 24 hours.

[0028] The obtained product was characterized by X-ray diffractometer (XRD), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). Characterization results show that the obtained product is monetite nanosheets with a thickness of about 150 nm. Other results are similar to E...

Embodiment 3

[0030] First, dissolve 0.30 g of tetramethylammonium hydrogen sulfate in 50 ml of distilled water, then add calcium nitrate tetrahydrate and sodium dihydrogen phosphate so that the molar ratio of the two is 1.1, and stir evenly. The reaction solution was sonicated with an ultrasonic cell disruptor. The ultrasonic frequency is 20kHz, the processing time is 40min, and the power is 400W. After the reaction, the reaction solution was cooled to room temperature and filtered. The product was washed several times with distilled water and ethanol, respectively. Finally, the product was dried in a drying oven at a temperature of 60° C. and a drying time of 24 hours.

[0031] The obtained product was characterized by X-ray diffractometer (XRD), field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). Characterization results show that the obtained product is monetite nanosheets with a thickness of about 150 nm. Other results are similar to Exam...

Abstract

The invention relates to a monetite with a layer-shaped structure prepared by using an ultrasonic assistant and a preparation method thereof, and belongs to the technical field of biomedical materials. The method comprises the following steps: taking calcium salt and phosphate salt as raw materials and a cationic surface active agent as a template agent; introducing ultrasonic radiation into reaction liquid; and depositing the generated nanometer sheet-shaped monetite, wherein the thickness of the monetite is 20 to 300 mm. A nanometer sheet is formed into an order layer-shaped structure underthe action of the ultrasonic radiation. The method can be executed at the room temperature, has the advantages of low cost, simple operation and the like, facilitates the improvement of the mechanical property of the monetite, expands the application of the monetite in aspect of bone substitution, and has wide application prospect in the application field of biomedicine.

Description

technical field [0001] The invention relates to an ultrasonic-assisted preparation of monetite with an ordered layered structure and a preparation method thereof, belonging to the technical field of biomedical materials. Background technique [0002] Monetite (CaHPO 4 ) as a bioactive material has attracted increasing attention. Due to its good biocompatibility and bioactivity, monetite, as a calcium phosphate cement, is commonly used as a resorbable bone substitute material. However, compared with real bone, calcium phosphate bone cement has less load bearing and poor mechanical properties, which greatly limits its application. Biominerals in organisms are usually in a certain orderly growth form to enhance the mechanical properties of tissues, such as teeth, bones and shells, etc., which proves that ordered assembled structures can provide better mechanical properties. In addition, monetite is a precursor of hydroxyapatite (HAp). The biological activity, biocompatibili...
