23 Jul Core-shell structure metal/polymer nanofiber and preparation method thereof
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.
