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.
