Abstract

The invention discloses a medical artificial skeleton used material and a preparation method thereof. The material comprises 20-50 parts of graphene oxide, 20-75 parts of 3-phenylacrylyl chloride, 50-100 parts of methyl methacrylate, 0.5-2 parts of a catalyst, and 0.5-2 parts of an initiator. At first, graphene oxide is dispersed in a 3-phenylacrylyl chloride solution in parts by weight, the mixture is added into a reaction kettle, the catalyst is added, and a heating reaction is performed under the argon protection; then, methyl methacrylate is added into the reaction kettle, the initiator is added, a heating reaction is performed, cooling to the room temperature is performed after the reaction, and the medical artificial skeleton used material is obtained. The medical artificial skeleton used material is low in production cost and the reaction is simple; the introduction of graphene greatly enhances the strength of the medical artificial skeleton used material, and the material inhibits germ growth without influencing the compatibility of an artificial skeleton and biological tissue in a human body.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a medical artificial bone material and a preparation method thereof. Background technique [0002] Medical polymer materials are an important part of biomedical materials, mainly used in medical fields such as artificial organs, surgical repair, physical therapy rehabilitation, diagnostic examination, and disease treatment. As we all know, organisms are the most basic form of organic polymers, and organic polymers are the basis of life. The most important substances in the composition of animals and plants - protein, muscle, cellulose, starch, biological enzymes and pectin are all polymer compounds. Therefore, it can be said that the biological world is a huge source of natural polymers. The ubiquity of polymer compounds in the biological world determines their special status in the medical field. Among various materials, the molecular structure, chemical composition and physi...
