Description
Technical field
The present invention relates to nano electron device, field of nanocomposite materials, specifically belong to carbon nano-tube material field, is a kind of single multi-walled carbon nano-tubes dispersion liquid and preparation method thereof.
Background technology
Carbon nanotube (CNTs), as a kind of novel monodimension nanometer material, has unique structure, excellent physics and chemistry characteristic.In recent years, related application field is fast-developing, scientists successively have developed transistor (see Nature such as TansS, 1998,393:49 52.), sensor (see AdvancedMaterials such as ChenPC, 2010,22:1900-1904.), vibrator is (see Nature such as SazonovaV, 2004,431:284-287.) etc. based on the high performance device of single-root carbon nano-tube, the monodispersity of carbon nanotube is had higher requirement.At present, containing impurity such as catalyst metal particles, carbon nano-particle and decolorizing carbon in the carbon nanotube using the methods such as chemical vapour deposition, arc-over, laser evaporation to prepare; Meanwhile, the effect of Van der Waals force easily makes single-root carbon nano-tube attract each other and forms large coacervate.Therefore, improve purity and the dispersing property of carbon nanotube, significant to the development in the field such as nano electron device, nano composite material.
At present in carbon nanotube method of purification, Physical is complicated, time-consuming and efficiency is low.Chemical method can be purified by selective oxidation, the method of general employing directly carries out liquid-phase oxidation by nitric acid, hydrogen peroxide, concentrated nitric acid/vitriol oil (volume ratio 1:3) mixed acid solution etc., but the experiment parameter that these methods obtain is inconsistent, there is no unified comparison, and larger to the destruction of carbon nanotube structure.In carbon nanotube dispersed Journal of Sex Research, existing experiment is by using Sodium dodecylbenzene sulfonate (see NANOLETTERS such as M.F.Islam, 2003,3(2): 269-273.) and polyvinylpyrrolidone (see ChemicalPhysicsLetters such as MichaelJ.O'Connell, 2001, the dispersing property of carbon nanotube 342(3-4): 265-271.) is relatively improved as tensio-active agent, but still cannot obtain the single-root carbon nano-tube of dispersion, and the tensio-active agent in dispersion liquid is not easily removed.
Summary of the invention
The present invention in order to the single-root carbon nano-tube that solves currently available technology and cannot obtain disperseing and the problem not easily removed of tensio-active agent in dispersion liquid, provides a kind of single multi-walled carbon nano-tubes dispersion liquid and preparation method thereof.
The present invention is achieved by the following technical solutions: single multi-walled carbon nano-tubes dispersion liquid, is to strangle by the multi-walled carbon nano-tubes of 1g/L, the richness of 0.4g/L the polar solvent that alcohol and pH be more than or equal to 7 to form.
The tensio-active agent that the present invention adopts is that the richness with polar group strangles alcohol, because compared with non-polar solvent, the soccerballene with polar group is more easily dissolved in polar solvent (such as, water or alcohol).Richness strangles the polyhydroxy derivates of alcohol as soccerballene, is used as tensio-active agent in the present invention, mainly because richness strangles the soluble in water and alcohol polar solvent of alcohol.Simultaneously, the electron adsorption ability that its cage structure is very strong, can be interacted by π-π with multi-walled carbon nano-tubes sidewall and produce physical property and adsorb, weakening the Van der Waals force between multi-walled carbon nano-tubes, therefore effectively can improve dispersiveness and the stability of multi-walled carbon nano-tubes.
Wherein, the pH of polar solvent will be equal to or greater than 7.Reason mainly contains following two aspects: 1) purified multi-wall carbon nano-tube tube-surface can introduce the oxy radical such as hydroxyl, carboxyl, the solution defection of acid ion improves the dispersing property of multi-walled carbon nano-tubes, but acidic conditions can suppress dissociating of multi-walled carbon nano-tubes surface acid group particle.2) compare with sour environment, under alkaline environment, high energy barrier is not existed to the oxidation that richness strangles alcohol, at room temperature easily can realize, be convenient to obtain the oxy radicals such as hydroxyl.Simultaneously richly strangle the character that alcohol has weak acid, therefore alkaline environment can promote its dissociating in the solution, increases rich solvability of strangling alcohol, thus improves the dispersing property of carbon pipe.Further, described polar solvent is sodium hydrate methanol solution, and wherein the concentration of sodium hydroxide is 0.01g/L.
In addition, in order to more detailed explanation the present invention, provide the preparation method of described single multi-walled carbon nano-tubes dispersion liquid,
Operation I: multi-walled carbon nano-tubes is added in alkaline pretreating reagent solution, 40 DEG C of reflux 12h; Then pretreated multi-walled carbon nano-tubes is joined ultrasonic 30min in concentrated nitric acid/vitriol oil mixed acid solution that volume ratio is 1:3, filter after neutral with deionized water wash, dry, reclaim the multi-walled carbon nano-tubes obtaining purifying;
Operation II: the multi-walled carbon nano-tubes of purifying, richness strangle alcohol and polar solvent mixes, adopts ultrasonic vibration dispersion, obtains multi-walled carbon nano-tubes dispersion liquid;
Operation III: carry out centrifugation 30min to the multi-walled carbon nano-tubes dispersion liquid that operation II obtains, rotating speed is 4000 ~ 6000r/min, reclaims the supernatant liquor after centrifugation, obtains single multi-walled carbon nano-tubes dispersion liquid.
In this preparation method, the reason of multi-walled carbon nano-tubes being carried out to the purification of liquid-phase oxidation substep is: the 1) acting in conjunction of pretreating reagent and mixed acid solution, can catalyst-solvent metallic particles, impurity contained in multi-walled carbon nano-tubes after therefore purifying obviously reduces; 2) adopt the purification of nitration mixture ultrasonic substep and direct nitration mixture to reflux to carry out compared with purification, the former is less to multi-walled carbon nano-tubes structural damage, and can keep the intrinsic property of multi-walled carbon nano-tubes better.
The multi-walled carbon nano-tubes of above-mentioned purifying, its surface can the oxy radical such as functionalized hydroxyl, carboxyl.This is because the acting in conjunction of pretreating reagent and mixed acid solution can make the fault location rate initial oxidation of multi-walled carbon nano-tubes, also by decolorizing carbon and carbon nano-particle activation, can make the oxy radical such as functionalisation of surfaces hydroxyl, carboxyl of multi-walled carbon nano-tubes simultaneously.And the dispersing property of multi-walled carbon nano-tubes in polar solvent (water or alcohol) of purifying is improved.This is because the multi-wall carbon nano-tube tube-surface of purifying can introduce the oxy radical such as hydroxyl, carboxyl, the solution defection of contained acid ion makes multi-walled carbon nano-tubes surface band negative charge, strengthen the electrostatic repulsion between multi-walled carbon nano-tubes, and then improve the dispersing property of multi-walled carbon nano-tubes.
During embody rule, wherein operation I is the operation of multi-walled carbon nano-tubes, richness being strangled alcohol and polar solvent mixing.In this operation, multi-walled carbon nano-tubes can be mixed simultaneously, richness strangles alcohol and polar solvent; Also can first obtain after richness strangles alcoholic solution, remix multi-walled carbon nano-tubes; After first multi-walled carbon nano-tubes can also being mixed with polar solvent, then add richness and strangle alcohol.
Wherein, operation II carries out sonic oscillation to the mixed solution obtained in operation I, prepares the operation of dispersion liquid.Ultra-sonic oscillation can use the ultrasonic irradiation device of grooved, also can use other ultrasonic unit.The ultra-sonic oscillation time is relevant to the power stage of instrument, if irradiation time is shorter, makes dispersion become insufficient; Otherwise if irradiation time is longer, then the structure of multi-walled carbon nano-tubes can sustain damage, and affects the intrinsic property of multi-walled carbon nano-tubes.
Wherein, operation III dispersion liquid obtained in operation II is carried out centrifugation and reclaims the operation of supernatant liquor.This is the multi-walled carbon nano-tubes in order to stable dispersion non-in removal step II.And if centrifugation is excessively strong, then dispersed multi-walled carbon nano-tubes is also removed.Otherwise if excessively weak, this can not remove the multi-walled carbon nano-tubes not having to disperse.Therefore, preferably carry out centrifugal with the condition of 4000 ~ 6000rpm.By this operation III, the single multi-walled carbon nano-tubes dispersion liquid that can more uniformly be disperseed.
The present invention adopts richness to strangle alcohol as tensio-active agent, the multi-walled carbon nano-tubes of purifying is disperseed, a kind of uniform and stable single-root carbon nano-tube dispersion liquid is prepared by mixing, ultrasonic, centrifugal three-procedure, this will expand the Application Areas of carbon nanotube further, particularly significant in the development in the field such as nano electron device, nano composite material to it.
