Antibacterial nanocomposite film material of graphene oxide and lysozyme, preparation method and application of antibacterial nanocomposite film material as antibacterial material

Abstract

The invention relates to an antibacterial nanocomposite film material of graphene oxide and lysozyme, a preparation method and application of the antibacterial nanocomposite film material as an antibacterial material. In the preparation method of the antibacterial nanocomposite film material of graphene oxide and lysozyme, with a mixed solution of the lysozyme and the graphene oxide as a raw material, the antibacterial nanocomposite film material of graphene oxide and lysozyme is prepared by using a solution casting method, wherein a mass ratio of the lysozyme to the graphene oxide in the mixed solution of the lysozyme and the graphene oxide is (2-15):1. By using the preparation method, the antibacterial nanocomposite film material of graphene oxide and lysozyme can be obtained. The antibacterial nanocomposite film material of graphene oxide and lysozyme is applied as the antibacterial material. The composite film can be spread on surfaces of other solids to have an antibacterial protection effect. In the invention, a novel functional nanocomposite film material on the basis of a graphene oxide nano-plate and a lysozyme protein, which has a highly ordered structure, a controlled-release character and an antibacterial function, is designed and prepared.

AI Technical Summary

Problems solved by technology

Due to its strong bactericidal ability, lysozyme has a wide range of application values. Of course, as a water-soluble protein molecule, it has the general disadvantages of protein molecules, such as low mechanical strength, and it is difficult to form a continuous film structure on a solid surface. Poor stability, will dissolve rapidly in aqueous solution, etc.
