Abstract

The invention relates to a nanometer silver gelatine nanometer fiber film, which comprises the following parts: a gelatine nanometer fiber and a nanometer silver distributed in gelatine nanometer fiber homogeneously, wherein the nanometer silver particle attaches the surface of the gelatine nanometer fiber or in the fiber, the mean diameter of the gelatine nanometer fiber is 60-220nm, and the mean diameter of the nanometer silver is 4-50nm. The electrostatic spinning method comprises the following steps: making the spinning liquid by adding silver nitrate in gelatin-formic acid solution; getting the nanometer fiber film with silver ion by electrostatic spinning; deacidizing the silver ion in the fiber into the nanometer silver particle with ultraviolet irradiation method. The nanometer silver gelatine nanometer fiber film is used to make the artificial skin, the medical dressing, the hemostatic material and the sanitary cotton.

Description

technical field

[0001] The invention relates to a nanofiber film, in particular to a gelatin nanofiber film containing nano silver and its preparation method and application. Background technique

[0002] At present, the manufacture of nanofibers has become one of the focuses of the world. Nanofibers have smaller diameters and larger specific surface areas, thus making nanofibers versatile. Non-woven fabrics made of nanofibers have the characteristics of high air permeability, coupled with the large surface area of ​​nanofibers, they are often used to make medical dressings to promote wound recovery. The nanofiber membrane has high porosity, which is conducive to the evaporation of wound exudate and avoids the wound area; and oxygen can easily pass through, which is conducive to the respiration of wound tissue cells, the growth and regeneration of epithelial tissue, and accelerates wound healing. In addition, nanofibers can also be used to make high-efficiency filter mater...
