Abstract

The invention provides a kind of new way that graphene is prepared using ethanol as liquid phase planetary ball mill wet method.The preparation method specifically includes:Using the expanded graphite after high-temperature calcination as raw material, using ethanol as organic solution, peel off expanded graphite by planetary ball mill wet lapping machinery and obtain lamella than more complete, the larger graphene of crystalline size.This method simple production process, cost is low, and the graphene being prepared is less than dry type graphene defect, and lamella is more complete, and the application to later graphene provides broader prospect.

Description

A kind of new way that graphene is prepared using ethanol as liquid phase planetary ball mill wet method
Technical field
The present invention relates to a kind of new way that graphene is prepared using ethanol as liquid phase planetary ball mill wet method, belong to advanced and receive Rice material preparation process technical field.
Background technology
A kind of carbon material with bi-dimensional cellular shape structure of the graphene as monoatomic layer thickness, possesses huge ratio table Area and superior electron mobility and property stabilization, are widely used in the fields such as electronics, sensor, medicine and catalysis, are The wider research of nano composite material provides new thinking and direction.Various countries expert is become since graphene is found The focus of scholar's research, while it is also considered as improving the new material in the fields such as sensor, medicine and catalysis.China is graphite The most abundant country of resource, and big producer, but the deep processing to its high-tech is probed into and is still in the junior stage.Graphene Research is concentrated mainly on last decade, and also many problems need to study.Therefore, the preparation method for exploring grapheme material is one It is individual to still need to solve the problems, such as.It should be noted that preparation and its difficulty of single-layer graphene, therefore will lack with its similar nature Layer graphene is also classified as the category of graphene.
The preparation method of graphene is concentrated mainly on chemical stripping method, CVD growth method and physics stripping method at present, wherein changing The defects of learning the redox graphene that stripping method is prepared is more, and experimental period is grown, and the cost of CVD growth method is higher, therefore Short preparation period using graphite as raw material, cost is low, and experiment is simple and less physics stripping method the defects of graphene enjoys pass Note.What is commonly used in currently used physics stripping method is adhesive tape tear, mortar formula grinding, the methods of agitation grinding and ball milling.Wherein Adhesive tape method of Tearing efficiency is too low and the graphene quality of preparation is uneven, and the grinding of mortar formula and stirring ball-milling are because equipment carries in itself The crystalline size that the energy of confession is relatively low can not to be peeled off graphite well and prepare is smaller, although ball mill can provide higher grinding Energy, but the graphene edge defect that the impulsive force in grinding can make the graphene size of preparation smaller and prepare is more.It is existing The common disadvantages of physical separation methods be that obtained graphene general size is all smaller, and poor controllability.This will be very big Ground hinders application of the graphene in practical devices.
Therefore, in order to preferably using ball mill provide higher grinding energy and overcome impulsive force pair in mechanical milling process The destruction of graphite, research finds to use wet ball-milling environment, using ethanol as organic solution, be graphite in ball mill ball milling mistake Sufficient peptizaiton is provided in journey, reduces impulsive force of the mechanical milling process to graphite so that the graphene size being prepared compared with Greatly, defect is less, the drawbacks of preferably improving original dry type ball milling.
The content of the invention
It is an object of the invention to overcome the shortcomings of existing physics stripping method, there is provided using one kind using ethanol as liquid phase planet ball Grinding machine wet method prepares the new way of graphene.With simple production process, yield is high, graphene defect is less and crystal chi Very little more complete feature.The nano material of gained graphene can be used for the novel-section for improving the fields such as sensor, medicine and catalysis The prospect of material.Realizing the object of the invention technical scheme is:A kind of wet type mechanical milling method prepares the new way of graphene.Its feature It is:Weigh a certain amount of graphite to be placed in ceramic pot, after calcining certain time in the Muffle furnace of certain temperature, after calcining Expanded graphite be positioned over it is stand-by in brown glass vessel;Then a certain amount of expanded graphite is weighed, is placed in 100ml beaker In, then a certain amount of ethanol organic solution is poured into beaker, it is stand-by after ultrasonic agitation certain time;Aforesaid liquid is poured into In agate pot, rock to uniform state, then agate pot is placed on planetary ball mill, by certain rotating speed and certain time Afterwards, the liquid in agate pot is poured out, graphene is can obtain with after being freeze-dried certain time after being centrifuged with deionized water.This Method simple production process, gained graphene sheet layer is more complete and crystal grain size is larger, is provided for the application of graphene More excellent performance.Specific synthesis step is as follows:
1st, weigh 0.5-5g graphite be placed in ceramic pot and control graphite in ceramic pot shared volume ratio be 1:1.5-3, so After calcining 2-5h in the Muffle furnace at 250-400 DEG C afterwards, the expanded graphite after calcining is positioned in brown glass vessel and treated With;
2nd, 0.5-2g expanded graphite is weighed, is placed in beaker, then pours into 10-50ml ethanol organic solution in beaker, It is stand-by after ultrasonic agitation 30-90min;It is 1 to control the mol ratio of graphite and ethanol:2-7, ultrasonic power scope are 100-500W;
3rd, aforesaid liquid is poured into agate pot, rocks to uniform state, then agate pot is placed on planetary ball mill, passed through After 300-800 rpm/min and 2-8h, the liquid in agate pot is poured out, takes supernatant to be freeze-dried after being centrifuged with deionized water Graphene is can obtain after 24h.It is 1 to control pellet mass ratio:8-15.
