Abstract

The invention discloses a preparation method of a composite nano-fiber material with photo-electromagnetic characteristics, and relates to a preparation method of a composite nano-fiber material with photo-electromagnetic characteristics, and aims at solving the problems that the nano-fiber material prepared by the existing method is poor in chemical stability, complicated in operation, poor in biocompatibility and large in toxicity. The method comprises the following steps: 1, preparing water-soluble polyfluorene (PF-Na), synthesizing a polyfluorene monomer with 2,7-dibromofluorene and 1,3-dibromopropane, synthesizing 9,9-bi(3-bromine propyl)-2-benzofiurene PF with phenylenebisboronic acid and the polyfluorene monomer, and synthesizing water-soluble polyfluorene PF-Na with PF and mercaptoacetic acid; 2, synthesizing water-soluble Fe3O4 nano-particles by virtue of a hydrothermal method; and 3, preparing the composite nano-fiber material with the photo-electromagnetic characteristics by wet-mixing and electrostatic spinning methods. The preparation method is used for preparing the composite nano-fiber material with the photo-electromagnetic characteristics.

Description

technical field

[0001] The invention relates to a preparation method of a composite nanofiber material with photoelectromagnetic properties. Background technique

[0002] In July 1990, the first international nanotechnology conference officially announced that nanomaterial science has become a new branch of material science. Since then, nanomaterials have attracted great interest and widespread attention from all over the world. In recent years, especially research on nanofibers and their applications has become a frontier hotspot. The small size effect of nanofiber materials makes them have excellent optical, electrical, magnetic, thermal and other properties, making them widely used in physics, chemistry, biology, medicine and other fields.
