Abstract
The invention discloses a method for preparing porous nanofibers through electrostatic spinning in combination with a double-solvent technology. The method concretely includes the steps that electrostatic spinning is performed on a prepared spinning solution to obtain nanofibers, then double-solvent treatment, freezing and low-pressure drying are sequentially performed on the nanofibers, and finally the porous nanofibers are obtained. Through the combination of electrostatic spinning, the freezing and drying technology and the double-solvent technology, the porous nanofibers controllable in porous structure are obtained, porous structures are arranged on the surfaces of the porous nanfibers, and while the wide application range is guaranteed, a large specific surface area can be achieved; the nanofibers are compact in interior and high in mechanical property and has broad application prospects in the fields of biological tissue engineering, filtering materials, catalyst carriers, fuel cells and others.
