Abstract

The invention relates to a barium titanate-graphene composite material and a preparation method and application thereof, belongs to the technical field of nano materials, and solves the technical problem of accelerated healing in each stage of wound repair, and the preparation method comprises the following steps: S1, preparing a graphene dispersion liquid; s2, a 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride solution and N-hydroxysuccinimide are added into the graphene dispersion liquid, and the graphene dispersion liquid is subjected to ultrasonic dispersion; s3, centrifuging to obtain a precipitate, cleaning, and dispersing into ultrapure water; and S4, dropwise adding aminated nano barium titanate, stirring at room temperature, cleaning, and drying to obtain the barium titanate-graphene composite material. The barium titanate-graphene composite material prepared by the invention is used in drugs for resisting bacteria and promoting cell proliferation and migration, especially in drugs for wound healing, the antibacterial effect of the composite material can be improved, and the inflammation period can be accelerated; after certain extrusion is applied to the wound, micro-current can be generated, so that a proliferation period and a mature period are promoted, and the whole wound repairing process is accelerated.

Description

technical field [0001] The invention belongs to the technical field of nanomaterials, and in particular relates to a barium titanate-graphene composite material and a preparation method and application thereof. Background technique [0002] The process of wound healing is a multi-stage and orderly physiological process, which mainly includes three stages: inflammation, proliferation and maturation. In the inflammatory stage, it is easy to be infected by bacteria, and the extensive use of antibiotics produces super bacteria, thereby delaying wound healing; in the proliferation and maturation stages, the proliferation and migration of fibroblasts and keratinocytes play an important role, so the development of antibacterial and drugs that promote cell proliferation and migration become important challenges for wound healing. [0003] Currently, a variety of nanomaterials are widely used to accelerate the wound healing process. However, most of them are only designed for a sin...
