Medical nano fiber enhanced composite material and preparation method thereof

Abstract

The invention relates to a medical nano fiber enhanced composite material. The composite material comprises a base material and nano short fiber, wherein the nano short fiber keeps a crystal form andis uniformly distributed in the base material, and the nano short fiber accounts for 1-50 mass percent of the composite material. The composite material has the advantage that a single-component polymer material has high break elongation and high flexibility, has little damage to blood vessels and other tissues, has high tensile strength and high break elongation in human tissues, and greatly improves the tensile strength of the material. The medical nano fiber enhanced composite material has high biocompatibility and biodegradability, and can meet clinical demands of medical materials.

Description

technical field

[0001] The invention relates to the technical field of nanofiber composite materials, in particular to a medical nanofiber reinforced composite material and a preparation method thereof. Background technique

[0002] Various tissues and organs in the human body may be abnormal or damaged. At present, the transplantation of tissues and organs is mainly used to restore their functions. In this process, a large amount of biological materials are needed to support the normal work of tissues and organs, such as stents, Ligation clips, etc., materials with good biocompatibility and biodegradability can finally form new functional tissues with the further proliferation and differentiation of cells and the degradation and absorption of materials to achieve the purpose of repairing defective tissues. The demand in the market is also increasing.

[0003] Medical materials prepared from single-component polymer raw materials have high elongation at break, good flexibil...
