Abstract
A kind of new graphite physical stripping means produces graphene, and the general principle of this method is：Ultrafine carbon fiber bistrique scraped finish high purity graphite rod surface under vacuum conditions, it will peel off graphite from level to level.The method product can be easily separated with raw material, good product quality, and production cost is low.
Description
Technical field
The present invention relates to a kind of production method of graphene and device, is particularly produced with high purity graphite rod mechanical stripping
The method and apparatus of graphene.
Background technology
Graphene is a kind of with good flexibility, the two-dimensional material of electrical property.You need to add is that said on stricti jurise,
Graphene is a kind of sheet of individual layer；But due to the preparation difficulty of single-layer graphene, typically also the stone with similar performance
In the category for also ranging graphene of the black alkene less than 10 layers.
At present, the method that prepared by graphene mainly has：Chemically grown method and physics stripping method.It is low compared to efficiency, uncomfortable
Together in the chemically grown method of industrialized mass production, physics stripping method mainly uses cheap graphite as raw material, by stone
Smoky quartz body, which applies mechanical force, makes graphite layers peeling-off, breaks the Van der Waals force of graphite layers, forms monolithic graphite alkene or widow
Layer graphene.Graphite powder is used to produce graphene for raw material physics stripping method, this physical separation methods have industrial prospect
With suitable large-scale production, but product separates difficulty with raw material.
The content of the invention
It is an object of the invention to provide a kind of new graphite physical stripping means to produce graphene, while product and raw material
It can be easily separated, good product quality, production cost is low.The general principle of this method is：Ultrafine carbon fiber bistrique is under vacuum conditions
Scraped finish high purity graphite rod surface, it will peel off graphite from level to level.The graphite rod refers to bulk graphite, includes graphite pole, graphite side
Rod, graphite cake, graphite blocks etc..
Realizing the device of the above method mainly includes：Vacuum work chamber, grinding head device, vavuum pump, graphite rod feed arrangement,
Controller.Grinding head device, graphite rod feed arrangement are installed inside the vacuum work chamber, and connect vavuum pump, closes vacuum
Working chamber can vacuumize behind the door.The grinding head device is mainly by grinding head motor, superfine fibre beam bistrique and bistrique motion control
Device forms.The graphite rod feed arrangement is mainly made up of graphite rod feeding clamp and limiting and fixing device.
Brief description of the drawings
Fig. 1 is schematic device, wherein 11 --- vacuum work chamber, 12 --- bistrique, 13 --- graphite rod.
Embodiment
A kind of graphite rod physics stripping prepares the device of graphene, mainly by vacuum work chamber, grinding head device, vavuum pump,
Graphite rod feed arrangement and controller composition.Described vacuum work chamber is the 800 millimeters high 1200 millimeters box hat cavity of diameter,
The inside is provided with grinding head device, graphite rod feed arrangement, and connects vavuum pump, can be vacuumized after closing vacuum work chamber door.
The grinding head device is mainly made up of grinding head motor, superfine fibre beam bistrique and bistrique motion control device.The superfine fibre
Beam bistrique is ultrafine carbon fiber beam bistrique.The bistrique motion control device can control bistrique to be in close contact with graphite rod.Institute
Graphite rod feed arrangement is stated mainly to be made up of graphite rod feeding clamp and limiting and fixing device.The controller can control vacuum
Pump, grinding head motor, the working condition of bistrique motion control device.
The device workflow that graphite rod physics stripping prepares graphene is as follows：Graphite rod is entered into feed collet installed in graphite rod
Tool, the door of vacuum work chamber is closed, open vavuum pump and vacuumize, bistrique motion control device moves on to bistrique close with graphite rod
Contact, grinding head motor are started working, and ultrafine carbon fiber beam bistrique produces stone in graphite rod mantle friction, by graphite rod phased separation
Black alkene.
