Description

A kind of method that microwave prepares CNT
Technical field
The present invention relates to a kind of method that microwave prepares CNT, belong to the technical field of material preparation.
Background technology
Carbon nanomaterial, such as CNT (CNTs), carbon nano-fiber (CNFs), graphene etc. are due to its highly significant Unique property, such as tensile strength, modulus of elasticity, electric conductivity, the heat-conductive characteristic of superelevation etc. cause scientists Huge concern, these materials are described as most potential material of next epoch.Wherein CNTs is by single or multiple lift stone Black alkene is crimped around same center according to certain angle, the big fullerene envelope of the hemispherical that two ends are formed by five-membered ring and heptatomic ring Firmly formed.CNT is the hexagon net constituted after carbon atom is bonded completely by 3 carbon atoms of sp2 hydridization and surrounding The face of cylinder that network planar structure is surrounded.The cylinder-like structure of this bending can produce quantum confinement and σ-π hydridization again, add The pi-electron delocalization structure that sp2 hydridization is produced imparts the excellent optics of CNTs, electricity, magnetic property.Moreover, CNTs Axial arrangement also imparts the excellent axial modulus and intensity of CNTs, is for strengthening the preferable material of composite materials property Material.
So far, synthesis CNTs method mainly has chemical deposition, arc process, laser ablation method, gas phase catalysis life Regular way etc..The harsh experiment condition of these synthetic methods needs, such as inert gas shielding, HTHP etc., substantially increase Danger in building-up process.The cost of instrument is also improved simultaneously.The invention provides a kind of synthesis of household microwave oven CNTs method, it is simple to operate, and CNTs can be synthesized under normal atmospheric atmosphere.
The content of the invention
Technical problem:It is an object of the invention to provide a kind of method that microwave prepares CNT, this method prepares carbon and received Mitron is simple and easy to apply, with low cost, can be mass-produced.
Technical scheme:The invention provides a kind of method that microwave prepares CNT, by conductive metallic material and two cyclopentadienyls Iron is well mixed in a mixer, and both mixtures are directly carried out into microwave heating afterwards, and conductive metallic material absorbs microwave It is brought rapidly up, system temperature rise, ferrocene resolves into Fe nanometer particles and cyclopentadienyl group, Fe nanometer particles catalysis ring penta 2 Alkenyl generates CNT.The preparation method is specific as follows:Conductive metallic material and ferrocene are well mixed, incite somebody to action both afterwards The heating of mixture microwave, heating finishes and obtains CNT.
Wherein:
Described conductive metallic material is copper product, Mo, iron material, Steel material.
