Problems solved by technology

At present, three-dimensional nanostructures are mainly prepared by the template method, but the crystallinity of the nanomaterials prepared by the template method is relatively poor, and the removal of the template is difficult, which increases the cost and is not conducive to the large-scale industrialization of materials.

Abstract

The invention discloses a carbon nano tube-doped ferric oxide three-dimensional nanometer material and a preparation method thereof, which relate to the technical field of the preparation of nanometer material. In the method, 1, 4 butylene glycol is used as a solvent, an acidified carbon nano tube is used as a doped phase, soluble trivalent ferric salt and ethylene diamine are used as raw materials, the materials are mixed at room temperature to form a uniform suspension, the uniform suspension is transferred into a mixed system to a stainless steel reaction liner, and stainless steel reaction liner is sealed for the uniform suspension to react in a baking oven at 150 to 200 degrees centigrade for 10 to 20 hours to obtain carbon nano tube-doped ferric oxide powder. The nano powder has a cuboid structure assembled by nano particles, and the cuboid has a length of between 0.1 and 0.5 mu m and a width of between 0.05 and 0.2 mu m. The method of the invention is simple. A solvent heating method is used for the first time to prepare a cuboid material assembled by doped ferric oxide nano particles of the three-dimensional carbon nano tube, thereby expanding the preparation field of the ferric oxide material.

Description

technical field [0001] The invention relates to the technical field of preparation of nanomaterials, in particular to a preparation method of a carbon nanotube-doped iron oxide three-dimensional nanostructure material. Background technique [0002] Carbon nanotubes have attracted widespread attention in the scientific community for their excellent magnetic, electrical, mechanical properties, wave absorption and unique hollow structure. Ferroferric oxide nanomaterials are widely used in high-density magnetic recording materials, for data storage, as well as for the preparation of wave-absorbing materials, electrostatic printing inks, broadband transformers, noise filters, and communication transformers. Iron oxide nanomaterials doped with carbon nanotubes will show more excellent magnetic, electrical and wave-absorbing properties, and have wider application prospects. [0003] Patent (CN 1743387A) discloses a preparation method of ferric oxide-coated carbon nanotube magnetic...
