Embodiment
Heteroatoms nano carbon microsphere of the present invention is a kind of polyhedron carbon of being organized of multilayer graphite linings structure by sealing bunch.The graphite linings of nano carbon microsphere shell, middle all is six membered ring partly, in the corner and turnover partly then form by five-membered ring, each carbon atom is all Sp
2Structure.The special layers graphite-structure of nano carbon microsphere makes it have advantages such as high heat conductivity, electroconductibility, structural strength, stability.
The nano carbon microsphere of this heteroatoms, its shell is the polyhedral structure of complete closure, this point is identical with the nano carbon microsphere of full carbon, but in the outside graphite shell of the polyhedron carbon of this heteroatoms nano carbon microsphere bunch, the carbon atom of part is replaced by heteroatomss such as nitrogen, boron, phosphorus or sulphur, then be different from general nano carbon microsphere, as shown in Figure 1.This makes the graphite shell of original pure carbon structure because of heteroatomic existence such as nitrogen, boron, phosphorus and/or sulphur, characteristic with polyelectrons or hole, and become a kind of nano-sized carbon particle of tool heteroatoms characteristic, please refer to Fig. 2, system shows the heteroatoms nano carbon microsphere electron spinning spectrum (ESR) at room temperature of doped with boron (B), as we know from the figure, the heteroatoms nano carbon microsphere of this doped with boron has unpaired electron (Lonepair).
There is a spot of carbon to be replaced on the nano carbon microsphere graphite linings by nitrogen, boron, phosphorus and/or sulphur, and the six membered ring of unlikely change graphite or five-membered ring structure, each atom on it (comprising adulterated heteroatoms) still is sp
2Blend together track construction, still have the characteristic of class graphite and the structure of many unsaturated double bonds.Because N or B atom can be inclined to sp
3Configuration, therefore, heteroatoms appears at nano carbon microsphere graphite shell can cause the graphite floor height of the ability of the thermal conduction of graphite layers and electron transport than pure carbon.Please refer to Fig. 3, is high resolution electron microscope (HREM) (HRSEM) photo of heteroatoms nano carbon microsphere.
One of feature of the present invention is, utilizes the characteristic of electronics more than mixed on the heteroatoms nano carbon microsphere graphite linings nitrogen, phosphorus, boron or the sulphur or electron deficiency, makes it to polar solvent (water) preferable avidity be arranged, and it is dispersed is dissolved in the solution.In addition, rely on heteroatomic reactivities such as nitrogen, phosphorus, boron or sulphur, but bond (or coordination bond) hydrogen atom, alkyl, alkoxyl group, halogen, hydroxy, amino, atoms metal or organometallic complex make its electrically charged dispersiveness that afterwards more increases solution.Bond on heteroatoms is with the difference of general functional groupization modification: can become SP during the heteroatoms bond
3Configuration is not destroyed the complete of graphite linings; General functional groupization modification then can be opened two keys and be destroyed the structural integrity (destroying two keys resonance) of graphite linings, has also destroyed the heat conductivity of graphite face.For example, be example with doping nitrogen (N) nano carbon microsphere (Doped-N Nanocapsules), bond hydrogen proton (H on the N atom
+) after, can be to the N atom with charge transfer, make Doped-N Nanocapsule particle positively charged (as shown in Figure 4), and increase heteroatoms nano carbon microsphere and polar fluid (for example: the reactive force organic solvents such as water, alcohols) (solubleness), so do not need additionally to use any interfacial agent promptly to have splendid dispersiveness.In addition, nano carbon microsphere is because its particle diameter (between most about 30～40nm), has extraordinary flowing property between 1～100nm in the heat abstractor that uses the fluid channel design.
In known techniques, have with nano carbon material for example nanometer carbon black or CNT (carbon nano-tube), hollow or interior metallic pure carbon nano carbon microsphere etc., as the additive of lifting fluid thermal conduction effect.Yet the heat conduction of pure carbon graphite-structure and conduction tool directivity are in the plane of the parallel graphite linings high heat conduction of tool () property, at direction heat conduction () the property extreme difference of vertical graphite linings.Therefore outer graphite linings can't effectively conduct heat to carbon bunch particulate inside.In addition, influence the factor of nano-fluid heat conductivity, be outside one's consideration except the thermal conduction of fluid and solute itself, the mobility of the nanoparticle that is added in fluid also has very big influence; The heteroatoms nano carbon microsphere contains electronics or hole, in polar solvent, have than the easier dispersion of other pure carbon nano carbon microsphere (or carbon material), with the advantage of upgrading, therefore be more suitable for adding material as the nano heat-conductive fluidic.
The shell of heteroatoms nano carbon microsphere is the multilayer graphite-structure, inside can be hollow (hollow), or the metal of filling agent magnetic, metal oxide, metallic carbide, metallic sulfide, metal nitride, metal boride or metal alloy be in its inside, and the content of metal can be 0.1wt% to 80wt%.This metal or its compound can comprise atoms metal or its combinations such as Sc, V, Cr, Fe, Co, Ni, Cu, Y, Zr, Mo, Ru, Rh, Pd, La, Ce, Pr, Nd, Gd, Tb, Al, Zn, Dy, Ho, Er, Tm, Lu, Ta, Os, Ir, Pt, Th or U.
For making the heteroatoms nano carbon microsphere be easier to be dispersed in uniformly in this fluid, the present invention further relies on the mode of chemical reaction, with the heteroatoms (N on specific molecule and the heteroatoms nano carbon microsphere graphite linings, B, P or S atom) bond, make heteroatoms nano carbon microsphere bond (or coordination bond) hydrogen atom, alkyl, alkoxyl group, halogen, hydroxy, amino, atoms metal or organometallic complex, make its electrically charged back and (for example: water more increase convection cell, organic solvents such as alcohols) dispersiveness between, so the present invention does not need to use any extra interfacial agent promptly to have splendid dispersiveness.
