Embodiment 1

[0029] Directly select pure magnesium rolling materials with magnesium content ≥ 99.9%, and process them into several rods with a diameter of 10mm*20mm by wire cutting. After polishing with sandpaper, remove the oxide layer during cutting, put them into glass bottles, and then Put a certain amount of absolute ethanol to submerge it. Then carry out ultrasonic cleaning, the time is about 15 minutes each time, until it is cleaned. After taking it out and drying it, put it in a clean bottle for later use.

[0030] The chemical composition of the prepared solution: 2 grams of Na 3 PO 4 , 0.3g KCl, 0.25KH 2 PO 4 , 10 grams of NaCl, add 500 mL of distilled water to prepare 500 mL of corrosion degradation solution, and put it into a clean bottle for later use.

[0031] Put 5 prepared pure magnesium rods into 5 clean test tubes with a volume of 50mL, and then use a pipette to draw 35mL of the prepared solution, and drop them into the test tubes with magnesium rods respectively. P...

Abstract

The purpose of the present invention is to provide a brand-new whisker fiber material and its preparation method, characterized in that: the shape of the whisker fiber material is branched or flake, the aspect ratio is more than or equal to 10 times, and the main component is magnesium phosphate Or magnesium hydrogen phosphate salt containing crystal water compounds. The whisker fiber material is prepared by a solid + liquid soaking and mixing method, has antibacterial effects on Escherichia coli, Staphylococcus aureus and Candida albicans, and can be widely used as biomedical materials. It has the characteristics of simple and convenient preparation method, low equipment requirement, low cost and the like.

Description

technical field [0001] The invention relates to the field of whisker fiber materials, and in particular provides a novel whisker fiber material and a preparation method thereof. Background technique [0002] With the rapid development of modern high-tech, the demand for whisker fiber materials is expanding day by day, and the technology for preparing whisker fiber materials is also constantly updated and developed. The variety of new whisker materials is gradually expanding, and the application range of whisker fiber materials is extended. In various fields, from the 1940s to the 1960s, whisker fiber preparation technology and theoretical research began, to the initial application and large-scale production in the 1970s-1980s, and then to the high-tech era in the early 21st century, whisker fiber products have already More than 100 kinds of whisker fiber materials such as metals, oxides, carbides, nitrides, borides, and inorganic salts have been developed. They are widely u...
