23 Jul Foldable multilayer cross-linked composite fiber net film as well as preparation method and application thereof
Abstract
The invention belongs to the field of high polymer materials and discloses a foldable multilayer cross-linked composite fiber net film as well as a preparation method and an application thereof. Superfine high-polymer fibers are prepared from a solution of a high polymer material or a solution of the high polymer material and a support through electrostatic spinning and subjected to solvent annealing treatment, and then the fiber net film is obtained; the composite fiber net film adopts a three-dimensional support structure, porous fiber gaps are kept inside, and the whole composite fiber net film can be folded and expanded; the superfine high-polymer fibers are placed on an expansible and/or contractible device when subjected to solvent annealing treatment. The preparation method is simple, feasible and good in repeatability; besides, the composite fiber net film adopts multilayer crosslinking, can be folded and expanded, has excellent performance and can be applied to fields of tissue engineering scaffolds, drug release carriers, protection materials, filter materials and battery separators.
