Embodiment 1
[0022] Choose Mg 65 Zn 30 Ca 5 The bulk sample of amorphous alloy is soaked in a test tube filled with PBS solution, soaked at room temperature for 3 hours for corrosion degradation reaction, and a white product is formed on the surface of the alloy and in the solution. Then take out the magnesium-based amorphous alloy, take another PBS solution to clean the alloy surface, centrifuge the cleaned solution and soaked solution at a speed of 8000r / min, filter off the supernatant, and add absolute ethanol to the obtained precipitate for washing , and then centrifuged with a centrifuge. After repeated washing and centrifugation for 7 times, the obtained precipitate was suspended in absolute ethanol again, and the obtained white suspension was placed in a constant temperature drying oven at 60°C for drying. After the absolute ethanol was completely volatilized A white powdery product was obtained.
[0023] The components of the PBS solution used are NaCl 8.01g / L, KCl 0.20g / L, NaCl...

Abstract
The invention discloses porous magnesium salt nanofiber synthesized from magnesium-based amorphous alloys and a preparation method of the nanofiber. By use of the characteristics that amorphous alloyshave ingredient and structure uniformity and controllable corrosion degradation rate, the magnesium-based amorphous alloys with good biocompatibility are taken as raw materials and subjected to a corrosion degradation reaction in a PBS solution of a simulated body fluid under the conditions of room temperature, normal pressure and no catalyst with a simple solution soaking method, the porous magnesium salt nanofiber is synthesized, the nanofiber material is rapidly and directly synthesized from blocky amorphous materials, and the defects that existing magnesium salt nanofiber synthesis methods are complicated, high in production cost and not favorable for large-scale production are overcome. The magnesium salt nanofiber has a large number of nanoscale holes and can be dissolved again after being soaked in the simulated body fluid. Therefore, the porous magnesium salt nanofiber can be used as a drug sustained release carrier material and has good application prospects in the field of biological medical materials.
Description
technical field [0001] The invention belongs to the field of nanomaterial preparation, and in particular relates to a porous magnesium salt nanofiber synthesized by a magnesium-based amorphous alloy and a preparation method thereof. Background technique [0002] Dielectric and semiconducting nanomaterials made of one-dimensional materials are widely used in advanced energy storage and energy collection devices, catalyst supports, sensors, flexible electronics, lightweight structural composites, construction materials, insulating materials, cutting tools, and thin films . Nanowires, nanowhiskers, nanofibers, nanotubes and other one-dimensional nanostructure materials have excellent performance in improving the optical, electrical, thermal and mechanical properties of functional materials and composite materials. These performance gains are significantly stronger than those achieved by adding micron- or nano-sized particles. [0003] Compared with the synthesis of 2D materia...
