Description

A kind of device and preparation method for quickly producing graphene crystal

Technical field

The present invention relates to a kind of devices and preparation method for quickly producing graphene crystal.

Background technique

Graphene be one kind by carbon atom with sp²Hybridized orbit forms the Two-dimensional Carbon nanometer material that hexangle type is in honeycomb lattice Material, it optics, electricity, mechanics, materialogy, micro-nano technology, the energy, in terms of play an important role.Currently, There are many kinds of the existing methods for producing graphene, wherein common method has mechanical stripping method, oxidation-reduction method, epitaxial growth Method, chemical vapour deposition technique in these methods, there is that the production cost is very high, and user can not receive for product price, some production Complex process, it is not easy to operate, the pollution that some generates in process of production is too big, and is shown using the above method A common feature be the graphene produced quality it is undesirable, be not able to satisfy requirement.

Summary of the invention

To overcome in existing situation, in common production method, there is that the production cost is very high, product price allows user can not Receive, some production technologies are complicated, it is not easy to operate, the pollution that some generates in process of production is too big, and more than use The common feature that these methods are shown is that the quality for the graphene produced is undesirable, is not able to satisfy requirement Deficiency, the present invention provides a kind of devices and preparation method for quickly producing graphene crystal, its operating process is easy, technique letter Single, production cost is low, and production process is pollution-free.

The technical solution adopted by the present invention to solve the technical problems is: taking the clay of 64% graphite powder addition 36% Powder is uniformly mixed, then prepares a roll shaft, and uniformly mixed graphite powder is then pressed into cylindrical graphite around roll shaft Roller, a then pedestal is arranged, the both ends of pedestal are respectively set left support and right support, and left support upper end is arranged sliding rail, on sliding rail Left bearing is set, and right bearing is arranged in right support upper end, then in submounts setting electric machine support and support spring, electric machine support Motor and motor shaft are installed, has attaching plug on motor, glass base is installed, glass base is placed above one above support spring The glass plate that block is cut out, then driving gear is installed on motor shaft, driving rack is installed in one end of roll shaft, then with transmission Left bearing and right bearing are set up in the two sides of the graphite roller of rack gear, are attached to graphite roller tightly on following glass plate, are ready to it Afterwards, power on, motor rotation, motor and motor shaft drive driving gear rotation, and driving gear drives driving rack to move back It is dynamic, with the movement of driving rack, be fixed on the graphite roller above driving rack also on following glass plate back and forth It is mobile, when graphite roller is rolled to the other end from one end of glass plate, just has a small amount of graphite powder and be sticked to above glass plate, this In a little a small amount of graphite powders, some is exactly the graphene of layer less, and some is exactly the graphene of single layer.

The invention has the advantages that keeping the technique for producing graphene simpler, cost is reduced, and the economy for reducing user is negative Load.
