Abstract

The invention relates to a method for preparing a core-shell structure metal / polymer nanofiber membrane. The prepared fiber membrane uses a polymer as a nuclear layer and uses a nano-metal as a shell layer; the polymer can be polyvinyl pyrrolidone, polyvinyl alcohol, polyoxyethylene, polylactic acid, polyacrylonitrile, hyaluronic acid, chitosan and the like; the nano-metal shell layer comes from metal salt silver nitrate or copper chloride. The core-shell structure metal / polymer nanofiber is prepared by utilizing the electrospinning technique; by controlling the process parameters, the concentration of polymer, the content of metal salt and the proportioning of solvents, the metal / polymer nanofiber membrane is prepared; the fiber membrane has high application value on tissue engineering, recovery of wound, drug transportation, photoelectricity and the like.

Description

technical field

[0001] The invention relates to a method for preparing metal / polymer nanofibers with a core-shell structure, which has broad research prospects in the fields of tissue engineering scaffolds, medical carriers, conductive nanomaterials, etc., and belongs to the field of preparation of functionalized nanofibers. Background technique

[0002] Electrospinning is a convenient method to prepare nanofibers ranging from tens of nanometers to micrometers. The resulting non-woven fabric has a high specific surface area, about 1 to 100m 2 / g. Due to the size effect of nanomaterials, the resulting nanofibers can often obtain many new phenomena and properties. The electrospinning process equipment includes: an injection tube containing a polymer solution, two electrodes, and a DC electrostatic generator and receiver capable of providing voltages in the kilovolt range. In the electrospinning technology, the spinning solution is charged with high-voltage static electricit...
