Background technology
With the discovery to graphene in 2004, seeking the research of other New Two Dimensional materials became last decade research
Focus.Molybdenum disulfide is the two-dimensional material of a species graphene property as transient metal sulfide.Block molybdenum disulfide is one
The indirect with gap semiconductors of kind, its with gap is 1.2eV, with the reduction of the molybdenum disulfide number of plies, especially when individual layer is reduced to, two
Molybdenum sulfide becomes direct with gap semiconductors, and its with gap increases to 1.8eV.Just because of this, molybdenum disulfide will be one kind in electricity
, optics, semiconductor applications have the two-dimension nano materials of particularly significant application prospect.
At present, the preparation method of molybdenum disulfide film, mainly have two kinds of " from top to bottom " and " from bottom to top "." from lower and
On " method is usually chemical vapor deposition (CVD) method, mainly using different molybdenum source and sulphur source under different reaction conditions
Class graphene molybdenum disulfide is deposited on substrate to be reacted, and the molybdenum disulfide film of large area is obtained by being vapor-deposited.Although
" from bottom to top " method can obtain large-sized molybdenum disulfide film, but electrical and optical properties are prepared not as good as " from top to bottom " method
Sample out, while have that reaction temperature is high, condition is harsh, reaction rate is low, preparation time is long, reacted tail gas is to ring
There is pollution in border." from top to bottom " method include micromechanical forces stripping method, lithium from graft process, liquid phase ultrasound stripping method, swash
Light method etc..Molybdenum disulfide sample defects prepared by this method of micromechanical forces stripping method are seldom, crystal structure is perfect, therefore have
Extraordinary optical and electrical properties, but this method prepare molybdenum disulfide sample size very little, yield poorly and repeatability it is poor.
Lithium ion graft process is compared with micromechanical forces stripping method, and efficiency high, the size of stripping are big, scope is wide, but complex operation, time-consuming takes

Further, recipient is arranged with the material barrel, the recipient includes circumferentially distributed polylith stripper plate, institute
State and be hinged successively between stripper plate, extruding back is connected by spring with material barrel inwall, stripper plate end face by canvas and
Material barrel inwall connects, and two end faces of material barrel are respectively arranged with charging aperture and discharge gate.
Further, the mandrel and grinding rod outer wall are coated with zirconium oxide or tungsten carbide coating.
Beneficial effects of the present invention：
1st, in mill processes, material is between material barrel inwall and grinding rod, between grinding rod and grinding rod and mills
Rub, extrude between rod and mandrel, because grinding rod and mandrel rotate in same direction, for this kind of stratiform material of molybdenum disulfide,
Formed between layers and reversely pull power, be advantageous to separate between layers and make material thinning, not only increase and material is ground
The uniformity of mill, and grinding efficiency and effect are improved, be advantageous to obtain few layer of molybdenum disulfide material of larger area.
2nd, the section of grinding rod is in cam-like, in grinding rod rotation process, between material barrel inwall and grinding rod, is milled
Gap between rod and grinding rod and between grinding rod and mandrel can change, so as to provide conjunction according to the circularity of material
Suitable extruding force, be advantageous to obtain strong extruding force and strong kneading force, make material between above-mentioned gap by reliable kneading force
And extruding force, so as to further improve grinding efficiency and effect.
3rd, material is rubbed in recipient, extruded, under spring force effect, the oriented contract of stripper plate or banding
Trend, material is integrally milled in the case where extruding environment, further increase grinding efficiency and effect, it is advantageously larger in obtaining
Few layer of molybdenum disulfide material of area.
4th, material is transmitted while mill, and continuous, stable operation can be achieved, effectively increase grinding efficiency.
5th, grinding rod outer wall is coated with zirconium oxide or tungsten carbide coating, improves the wearability of grinding rod.
