Abstract

The invention relates to a photo-electro-magnetic three-function banded coaxial nano cable array and a preparation method thereof, belonging to the technical field of nanometer material preparation. The method comprises the following five steps: (1) preparing Fe3O4 nanocrystalline coated with oleic acid by precipitation; (2) preparing a Tb(BA)3phen complex by precipitation; (3) preparing polymethyl methacrylate; (4) preparing spinning solution; and (5) preparing a [Fe3O4 / PANI / PMMA]@[Tb(BA)3phen / PMMA] photo-electro-magnetic three-function banded coaxial nano cable array by a coaxial electrospinning technology. The prepared banded coaxial nano cable array has good luminescence, conductivity and magnetism. The width of a banded coaxial nano cable is 10 microns, the thickness is less than 1 micron, and the length is greater than 500 microns. The method of the invention is simple and easy, and supports mass production. The novel nano structure material has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a photoelectromagnetic three-functional strip-shaped coaxial nanocable array and a preparation method thereof. Background technique [0002] The preparation and properties of one-dimensional nanostructured materials are one of the frontier hotspots in the field of material science research. Nanocables (Nanocables) have attracted great attention in recent years because of their unique properties, rich scientific connotations, broad application prospects and important strategic positions in future nanostructure devices. The research on coaxial nano-cables started in the mid-1990s, and developed rapidly after 2000. So far, people have successfully prepared hundreds of coaxial nano-cables by using different synthesis methods and different types of materials, such as: Fe / C, Zn / ZnO, C / C, SiC / C, SiGaN / SiO x N y And the three-layer structure of Fe-C-BN and α-Si 3 N ...
