Abstract

The invention discloses a composite material containing spider silk. The composite material is prepared from the following raw materials in parts by weight: 25-35 parts of spider silk, 5-10 parts of modified carbon nanotubes, 15-20 parts of polylactic acid, 3-8 parts of a nano-zinc oxide composite graphene improver, 1-5 parts of chitosan, 1-4 parts of seaweed polyphenol and 30-35 parts of an ethanol solvent. According to the composite material containing the spider silk, the spider silk, the polylactic acid and the ethanol solvent are matched, a fiber yarn structure is formed through electrostatic spinning, the antibacterial performance, the strength and the toughness performance of the product are enhanced by adding the modified carbon nanotubes and the nano-zinc oxide composite graphene improver as a synergistic enhancer, and the antibacterial performance, the strength and the toughness of the product are improved through adding and matching of chitosan and seaweed polyphenol. The compatibility among the raw materials is enhanced, and the comprehensive performance of the product is further improved.

Description

technical field [0001] The invention relates to the technical field of spider silk composite materials, in particular to a spider silk-containing composite material and a preparation method thereof and application in medical materials. Background technique [0002] Spider silk is a natural biological material, and it is expected to become an ideal tissue engineering scaffold due to its unique material composition, structure and good biocompatibility. Research has shown that the miracle of spider silk's perfect combination of high strength and high ductility is inextricably linked to the unique and delicate hierarchical microstructure inside spider silk. Spider silk is a natural protein fiber, and spider silk protein is composed of polypeptide chains composed of various amino acids in a certain way. The analysis showed that the amino acid composition of spider silk protein was mainly glycine and alanine, which accounted for about 70% of the amino acid content of spider silk ...
