Superfine fiber membrane as well as preparation method and application thereof

The invention provides a superfine fiber membrane as well as a preparation method and application thereof, the preparation method of the superfine fiber membrane comprises the following steps: adding an aliphatic polyester material, a hydrophilic material and capsaicin into a solvent, and stirring to obtain a spinning solution; placing the spinning solution in an injector of electrostatic spinning equipment, and performing electrostatic spinning to prepare to obtain the superfine fiber membrane. According to the preparation method of the superfine fiber membrane, by using a co-solvent, the aliphatic polyester material, the hydrophilic material and the capsaicin are blended and dissolved by adopting a one-step dissolution method, the preparation of the capsaicin-loaded superfine fiber membrane is realized through an electrostatic spinning method, and the membrane has a relatively large specific surface area. As a drug carrier, the superfine fiber membrane has a positive effect on drug release, and has potentia
