23 Jul High-content sodium alginate nanofiber membrane and electrostatic spinning manufacturing method thereof
Abstract
The invention provides a high-content sodium alginate nanofiber membrane and an electrostatic spinning manufacturing method thereof. The material is formed by sodium alginate or sodium alginate and polyvinyl alcohol, wherein the absolute content of the sodium alginate is 42.5 wt% to 100 wt%, and average diameter of the fiber is 100 nm to 150 nm. A solvent used in a preparation process of an electrostatic spinning solution is deionized water, and a surfactant is TX-100 which is certificated by US Food and Drug Administration. The manufacturing method is simple and feasible, and the high-content sodium alginate nanofiber membrane is not added with any hazardous substance. The manufactured sodium alginate nanofiber membrane is characterized by high content of sodium alginate, thin average diameter, and high porosity. The sodium alginate nanofiber membrane can be applied in the fields of wound dressing and tissue engineering (for example, a support material), etc.
