Description
Technical field
The present invention relates to a kind of low temperature preparation method of novel easy hydroxyl functional Graphene, belong to novel carbon nanomaterial field.
Background technology
Graphene is a kind of two-dimentional atomic structure of carbon of finding in recent years, and thickness in monolayer only is the graphite material of an atom thick, and has become one of at present the most popular research field.Graphene still is the basic structural unit of zero dimension soccerballene, one dimension carbon nanotube and three-dimensional graphite, thereby has the character of many uniquenesses.As big specific surface area, excellent electronic conduction character, excellent mechanical property and extra light quality.These unique character make it have huge application potential in biotechnology and life science, and it still makes nano electron device---the best materials of RF transistors.In addition, the derivative of its functionalization---graphene oxide also is a kind of important function material.
Existing preparation method of graphene mainly is a chemical Vapor deposition process.The main process of chemical Vapor deposition process is to be raw material with the hydrocarbon polymer, is serving as on the metallic membrane of catalyzer, and high-temperature catalytic decomposes raw material, in the presence of hydrogen, thereby obtains a layer graphene on its surface.But it needs higher temperature, and it is dangerous big and foreign matter content is more and limited its application that high temperature feeds hydrogen down.
Summary of the invention
Need high-temperature catalytic to cause dangerous bigger technical problem for solving existing graphene preparation method existence, the invention provides a kind of low temperature preparation method of hydroxyl functional Graphene.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of low temperature preparation method of hydroxyl functional Graphene, it is characterized in that: Graphite Powder 99 and potassium hydroxide solid are joined among the ball milling tank body, add at the ball milling tank body then and carry out spin, again ball grinder is put into ball mill, under air blast and normal temperature condition, after the continuous ball milling 10-16 of 200-400 rev/min speed hour, the ball milling product is transferred in the sample bottle with deionized water, and then with deionized water unreacted potassium hydroxide is removed, be neutral until solution.
The weight ratio of Graphite Powder 99 and oxyhydroxide is preferably 1:15 ~ 1:20, preferably 1:20.
The order number of the Graphite Powder 99 among the present invention is-100.
Spin is preferably selected agate ball for use among the present invention.Because potassium hydroxide is alkaline high, corrodibility is very strong, and other spheroids (as stainless steel iron ball or iron content mixture spheroid) easily are corroded.Agate ball then can not be corroded
The diameter of above-mentioned agate ball is 3mm.
Above-mentioned agate ball add-on accounts for 1/5th of agate jar volume.
The invention has the beneficial effects as follows: adopt aforesaid method, can obtain the hydroxyl Graphene at normal temperatures, this hydroxyl Graphene is laminated structure, and great amount of hydroxy group functional group is contained on its surface, and the internal structure of Graphene remains intact, and crystallization degree is higher.

Embodiment
With the 10mg specification is-100 purpose flaky graphite powder and 200mg potassium hydroxide solid, joins among the agate jar body of 250ml, and adding exsiccant diameter is that the agate ball of 3mm carries out ball milling, and add-on accounts for 1/5th of agate jar volume.Then ball grinder is put into ball mill, under air blast and normal temperature condition, after the continuous ball milling 10-16 of 200-400 rev/min speed hour, the ball milling product is transferred in the sample bottle of 20ml with the 10ml deionized water.Then it is packed into and change deionized water repeatedly in the dialysis tubing unreacted potassium hydroxide is removed, be neutral until solution.Obtain the hydroxyl Graphene of favorable dispersity.
Dispersant liquid drop on smooth monocrystalline silicon piece, is put into vacuum drying oven, and vacuum tightness is 0.1Pa, dried overnight.Obtain the chemical structure on Graphene surface after measuring by Fourier infrared spectrograph; It is laminated structure to utilize transmission electron microscope observation, and X-ray diffraction analysis finds that the grafting of hydroxyl does not change the internal structure of Graphene, and degree of crystallinity is good.
As can be seen from Figure 1, with to add 150mgKOH(be that the weight ratio of Graphite Powder 99 and oxyhydroxide is 1:15) compare, the weight ratio that adds 200mgKOH(and be Graphite Powder 99 and oxyhydroxide is 1:20) behind the ball milling, hydroxyl peak obviously strengthens (near the 3400cm-1), illustrates that the Graphene surface contains more hydroxy functional group.
By among Fig. 2 as can be seen, obtained flaky Graphene by above preparation method.
We can learn from Fig. 3, and the Graphene internal crystallization degree that adopts above preparation method to obtain good (peak is thin and sharp) illustrates that the hydroxyl Graphene that adopts present method to prepare is less to the destruction of its internal structure.
As can be seen from Figure 4, when rotating speed is 200r/min, obtain the product maximum (charateristic avsorption band of Graphene is positioned at about 260nm approximately) of Graphene.
Fig. 5. be that ball milling 4h, 8h, 16h after product have just been transferred to the deployment conditions in the deionized water from left to right successively among a figure, we can find that precipitation appears rapidly in ball milling 4h after product, and ball milling 8h and 16h then present more uniform dispersion liquid.Fig. 5. b figure is with spend the night deployment conditions after leaving standstill of above-mentioned three's solution, and finding spends the night leaves standstill the also appearance precipitation of back ball milling 8h, but ball milling 16h still present good dispersion state, thereby confirm that the best ball milling time is 10-16h.
