Description
Technical field
The present invention relates to a kind of continuous production tubular carbon nano-tube macroscopic body, and based on the method and apparatus preparing carbon nano-tube film in atmosphere open system of this macroscopic body, belong to technical field of nano material.
Background technology
Key in technical field herein and describe paragraph.Carbon pipe macroscopic body refers to the aggregate at least reaching the carbon nanotube of macro-scale in a dimension.The carbon nanotube blocks of one dimension carbon nano-tube fibre, Two-dimensional Carbon nano-tube film and three-dimensional can be divided into.In recent years the research of carbon pipe macroscopic body obtains development at full speed.Realize under macro-scale, keep the excellent properties of carbon nanotube under nanoscale to be technological difficulties.Carbon pipe film is assembled into by specific operation method by carbon pipe, has the high performance thin film of the characteristics such as light weight, high-strength, high connductivity, high heat conduction, electrochemical capacitance.Research shows, have the carbon pipe of nano aperture structure and film thereof at electrode material for super capacitor, fuel cell, the fields such as catalysis have potential using value.Such as by controlling diaphragm thickness, this bill of material reveals high conductivity and the perviousness to visible ray, can be used as the surrogate of indium tin oxides film.
The preparation method of current carbon pipe film mainly can be divided into solution method and chemical Vapor deposition process.Solution method is similar to traditional paper technology: be first dispersed in specific solvent by the carbon pipe after purifying and make slurry, then it is deposited on substrate by methods such as vacuum filtration, spin coating, LB embrane method or direct volatilizations.Isotropic carbon pipe film can be obtained in this way, carbon pipe stochastic distribution in film.But the large π key of carbon nano tube surface makes its neither hydrophilic also not oleophylic, is dissolved in existing any solvent hardly, makes carbon pipe not easily disperse.The dispersion of carbon pipe is the gordian technique of the method.Common way makes carbon pipe functionalization.But the carbon pipe film obtaining high-purity homogeneous phase needs again to go functionalization to it, adds the complicacy of the method.Chemical Vapor deposition process is a kind of very simple and effective method preparing carbon pipe film.The carbon pipe film of level or vertical orientation can be prepared.It is elder generation's deposit catalyst layers in particular substrate, then synthesized carbon tubing type, arrangement mode, purity etc. are regulated by the supply mode, temperature of reaction etc. of control carbon source, carrier gas, but the thickness of film and size are subject to the restriction of the size of catalyst activity and substrate, and preparation process is discontinuous.Another kind method is floating catalytic chemical Vapor deposition process, catalyzer passes into reaction zone with carbon source, carrier gas etc., form carbon nanotube, at cold zone formation of deposits carbon pipe film, but the directional property of carbon nanotube is bad in the film formed, the size of film depends on the caliber of reaction tubes and the length of cold zone and can not continuous production.
Chinese patent CN101665247A discloses a kind of method that liquid sealed vapor-phase flow catalytic reaction prepares carbon nano-tube film.Carbon raw material, metal catalyst and reaction promotor are input in vertical tubular resistance furnace and react, form carbon nano-tube film in the hydrogen gas stream, spun by the method for machinery.Because the width of film limits by the caliber of boiler tube, make the size-constrained of the film of preparation, industrialization demand can not be met.High-temperature hydrogen closed system, also exists potential danger, is unfavorable for suitability for industrialized production.
