Embodiment 1

[0056] Under mechanical stirring, mix 135mL deionized water, 105mL oleic acid and 60mL methanol evenly, then slowly add 150mL aqueous solution containing 10.5g sodium hydroxide, then slowly add 120mL aqueous solution containing 3.33g calcium chloride, and finally slowly add 180mL containing 9. 360g aqueous solution of sodium dihydrogen phosphate dihydrate; after stirring evenly, pour the solution into the reaction kettle, seal it, heat it to 180°C, and keep it warm for 26h. The solvothermal product consisted of a white milk at the bottom and a pale yellow supernatant, and by mixing the white milk and supernatant at a volume ratio of 4:1, a hydroxyapatite ultralong nanowire slurry was obtained and heated at 60 °C Keep warm for 30min. Take 6 mL of hydroxyapatite ultralong nanowire slurry and inject it into ethanol at room temperature through a syringe with a needle diameter of about 1100 μm (injection procedure: moving distance 2 cm and flow rate 5 mL / min). The macro-scale fibe...

Abstract

The invention provides a three-dimensional multistage highly-ordered hydroxyapatite super-long nanowire fiberboard-mud structure composite material, a preparation method and application thereof. The composite material is formed by assembling ordered structure macroscale fiber and organic matters, wherein the ordered structure macroscale fiber is formed by taking hydroxyapatite super-long nanowiresas the inorganic unit, the content of the hydroxyapatite super-long nanowire is 60-90wt.%, and the content of the organic matters is 10-40wt.%.

Description

technical field [0001] The invention belongs to the field of nanocomposite materials, and in particular relates to a three-dimensional multilevel highly ordered hydroxyapatite superlong nanowire fiber board-mud structure composite material and its preparation method and application. Background technique [0002] Structural materials are an indispensable class of materials. Whether it is high-end products such as spacecraft, aircraft, and ships, or daily necessities such as houses and household appliances, and biomedical materials, there are many demands for structural materials. With the development of structural materials, people have put forward higher requirements: low density (lightness, which is beneficial to reduce the effect on other structural components), high mechanical strength (with high Young's modulus and the ability to resist irreversible deformation) ), high toughness (has a high ability to resist destructive fracture of the material) and durability (can resi...
