A kind of preparation method of nanocomposite antibacterial dressing

Abstract

The invention provides a method for preparing a nano-compound antibacterial dressing. The antibacterial dressing is prepared by the following steps: preparing the following raw materials in a certain percentage: various precursors having different nano-scales, an emulsifier and surfactant, and stirring for 2-3 hours at a temperature T being 40-60 DEG C to obtain a dispersion of an antibacterial agent; adding the dispersion of the antibacterial agent into a water-soluble polymer solution with a certain concentration, and mechanically stirring for 12 hours to obtain a uniform solution; and freeze-drying the polymer solution to obtain the nano-compound antibacterial dressing. The nano-compound antibacterial dressing prepared by the method is wide in raw material source, low in cost, good in air permeability and remarkable in antibacterial and anti-ultraviolet effect.

Description

technical field

[0001] The invention discloses a preparation method of a nanocomposite antibacterial dressing, which belongs to the field of preparation of biomedical dressings. Background technique

[0002] The skin is an important organ of the human body, a natural barrier and a bridge of communication between the body and the outside world. Loss of skin tissue due to burns, trauma, and skin ulcers can lead to wound infection. Currently, one effective method of dealing with skin wounds is the use of wound dressings.

[0003] Traditional wound dressings include gauze, absorbent cotton, bandages, etc. However, from a medical point of view, these traditional wound dressings have limited clinical application because they do not have the properties of treating and repairing wounds, nor do they have antibacterial activity. Therefore, new medical dressings that can promote wound healing, have high antibacterial properties and are more convenient to use have gradually developed...
