Abstract

The invention relates to a tricolor flag type nano-belt array with three functions of anisotropy, conductivity and magneto-optic and a preparation method thereof, and belongs to the technical field of nano-material preparation. The method comprises the following five steps: (1) preparing oleic acid coated Fe3O4 nano-crystal by means of a precipitation method; (2) preparing a Tb(BA)3phen complex by the precipitation method; (3) preparing polymethyl methacrylate; (4) preparing a spinning solution; and (5) preparing a [Tb(BA)3phen / PMMA] / / [PANI / / PMMA] / / [Fe3O4 / PMMA] tricolor flag type nano-belt array with three functions of anisotropy, conductivity and magneto-optic by adopting an electrospinning technology and using two parallel spinnerets. The prepared tricolor flag type nano-belt array has three excellent functions of illumination, conducting anisotropy and magnetism. The method is simple and feasible and can be used for massive production, and the novel nano-structural material has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of preparation of nanometer materials, in particular to an anisotropic conductive electro-optical trifunctional tricolor flag nanobelt array and a preparation method thereof. Background technique [0002] The preparation and properties of nanoribbons are currently one of the frontier hotspots in materials science, condensed matter physics, chemistry and other disciplines. Nanoribbon is a kind of nanomaterial with ribbon structure synthesized by artificial method. Its cross section is a rectangular structure, its thickness is on the order of nanometers, its width can reach micron level, and its length can reach hundreds of microns, even several mm. Nanobelts have attracted great attention because of their novel structures different from tubes and wires, and their unique optical, electrical, and magnetic properties. [0003] The three colors of the strips in the tricolor flag represent different meanings, su...
