23 Jul Preparation method for controllable core-shell structure nanofiber
Abstract
The invention discloses a preparation method for controllable core-shell structure nanofiber and belongs to the field of functional nanofiber preparation. According to the preparation method for the controllable core-shell structure nanofiber, polymer is blended with micro-molecular cationic photoinitiator and fluorine-containing epoxy monomer, electro-spinning is performed under UV light irradiation by means of the characteristics that the macro molecule has high mobility, and the surface with a little of fluorine-containing compound is capable of migrating to the fiber surface, the functional fluorine-containing core-shell structure nanofiber with controllable thickness is prepared through controlling the dosage of the fluorine-containing monomer, wherein the core layer of the functional fluorine-containing core-shell structure nanofiber is polymer fiber while the surface is a fluorine-containing photo-polymerization cross-linked shell layer. The preparation method for the controllable core-shell structure nanofiber effectively prepares material through electro-spinning and photo-polymerization, the novel nanofiber has the excellent performances of the polymer fiber and fluorine-containing material, the performance is improved, and the application field is widened. The fiber has hydrophobic property, lipophobic property, pollution resistance, wearing resistance and the like, and the bio-compatibility is good; the nanofiber can be used for the fields of tissue engineering, wound repairing and the like, and the controllable core-shell thickness has high latent medical value in the drug sustained-release aspect.
