Polymer electrospun fibers, preparation method thereof and application thereof

Abstract

The invention discloses polymer electrospun fibers, which comprise the following components in percentage by mass: 80 to 100 percent of polymer and 0 to 20 percent of pH regulator, wherein the polymer is a hydrophilic polymer and / or slightly hydrophilic polymer. The fibers have better liquid absorptivity than the traditional fibers and can be widely used. The preparation method is simple in operation, can be adjusted according to actual needs and is suitable for industrial production. The invention also discloses a medicinal compound or fiber dressing prepared by using the polymer electrospun fibers, and the medicinal compound or the fiber dressing can be directly used for treating wounds and / or protecting the wounded from pollution. Compared with the traditional dressing, the medicinal compound or the fiber dressing have the advantages of reducing pains in the wounded, along with convenient removal.

Description

technical field

[0001] The invention relates to the technical field of preparing polymer electrostatic spinning fibers by using electrostatic spinning technology, in particular to a polymer electrostatic spinning fiber and its preparation method and its application in the preparation of medical composites. Background technique

[0002] There have been some patent reports and laboratory studies on electrospinning technology. In the process of electrospinning, an electric field is first formed on the surface of the liquid, and when the force of the electric field acts on the surface of the liquid, a charged liquid jet will be generated on the surface of the liquid. A liquid jet is stretched by being attracted to oppositely charged substances with the right electrical potential. As the liquid jet is stretched, it dries and solidifies, creating fibers. The stretched liquid jet can be solidified and dried by physical solidification such as cooling of the liquid, evaporation of ...
