Description

A kind of MWCNT/Fe 3o 4the preparation method of/ZnO nanocomposite
Technical field
The present invention relates to a kind of MWCNT/Fe 3o 4the preparation method of/ZnO nanocomposite.
Background technology
The function of multiple constituent element organically combines by nano composite material, make it to produce collaborative coupling effect, give material with the multifunctionality of novelty, in transducer, biological field, optical material and catalyst etc., show the unrivaled advantage of monocomponent nanocomposite material.Multi-walled carbon nano-tubes (MWCNT), with the electricity of the shape characteristic of its high length-diameter ratio, high surface and excellence, mechanics and thermal property, has been widely used at numerous areas tools such as catalysis, the energy, biomedicine, structure enhancings.Tri-iron tetroxide (Fe 3o 4) nano particle is a kind of important magnetic material, the magnetism characteristic because of its excellence makes it be all get most of the attention in industrial production or in scientific research.Work as Fe 3o 4when the particle diameter of nano particle is less than 30nm, particle embodies superparamagnetism at ambient temperature.Superparamagnetism Fe 3o 4nano particle has high magnetic permeability, without remanent magnetism, without advantages such as coercive force and high saturation magnetic field intensity, has broad application prospects in the field such as early diagnosis, target administration, information storage, separating substances of the major diseases such as magnetic resonance imaging, cancer and AIDS.Zinc oxide (ZnO) is a kind of important semi-conducting material, is used widely at chemical industry and biomedical sector as catalyst, desulfurizing agent, pressure sensitive, fluorescence imaging material.The compound of above three kinds of materials that have complementary functions can be composed undoubtedly with material with multifunctionality, greatly widens the application of material.
Ternary and the surface state of above Nano-composite materials to reaction condition and particle require very harsh, especially during the third deposition of material, if effectively control thermodynamics of reactions and kinetic parameter can make the indiscriminate deposition of particle.Such as, for MWCNT, Fe 3o 4with the compound of ZnO tri-kinds of nano materials composition, " polyalcohol one kettle way prepares CNT/Fe 3o 4the method of ZnO one-dimensional nano-composite material " report a kind of one kettle way in (application number: 201010563497.X) and prepare approach, article (Sui, J.H. that composite material prepared by this kind of method is delivered at it as inventor; Li, J.; Li, Z.G.; Cai, W., Synthesis and characterization of one-dimensional magnetic photocatalytic CNTs/Fe3O4-ZnOnanohybrids.Materials Chemistry and Physics2012,134, (1), stating 229-234.), is a kind of Fe 3o 4with ZnO respectively in the technology of MWCNT surface attachment, in this material, there is Fe 3o 4with MWCNT coupling and ZnO and MWCNT coupling.Because Fe 3o 4surface covered by polyalcohol, there is the surface energy lower than MWCNT, ZnO preferentially at MWCNT surface deposition, not at Fe 3o 4surface deposition, causes Fe 3o 4do not contact with each other between the two with ZnO, not there is Fe 3o 4and the coupling between ZnO.The MWCNT/Fe prepared in a conventional method 3o 4/ ZnO nano compound exists ZnO can not at Fe 3o 4surface coated shortcoming.
