Abstract

The invention discloses a method for rapidly peeling and transferring a graphene oxide leaching film to a substrate. The method specifically comprises the steps of firstly adding graphene oxide in water, forming graphene oxide dispersion liquid in an ultrasonic dispersion way, arranging the substrate on a sand core of a leaching flask, installing a leaching device, then pouring the prepared graphene oxide dispersion liquid into the leaching device, and starting leaching; then taking out the substrate which is attached with a leached graphene oxide film, and putting the substrate into an organic solvent, enabling the graphene oxide film to be rapidly formed through dewatering, and enabling the graphene oxide film to fall off the substrate; enabling the smooth substrate to be in direct contact with the floated graphene oxide film in the organic solvent, and enabling the graphene oxide film to transfer to be attached onto the substrate. Through the method disclosed by the invention, the drying time is not needed at all, and the time for peeling a thick film is greatly shortened; meanwhile, a thin film can also be peeled, a smooth graphene oxide film can be obtained, and the shape can be well maintained.

Description

A kind of quick stripping graphene oxide suction filtration film and the method for being transferred to substrate
Technical field
The present invention relates to a kind of quick stripping graphene oxide suction filtration film and the method that is transferred to substrate.Belong to graphite oxide The technical field that alkene suction filtration film is quickly peeled off and shifted.
Background technology
With the discovery of Graphene, its excellent electrical properties, mechanical property, thermal property and magnetic property cause people Extensive concern.Used as the important derivatives of Graphene, graphene oxide is also more and more paid attention to.Graphene oxide As a kind of new carbon of excellent performance, with cellular two-dimensional structure, due to special physics, chemical property, Such as specific surface area higher, higher porosity, containing abundant oxygen-containing functional group, the features such as asepsis environment-protecting.Graphene oxide with And its reduzate Graphene is in many fields, such as absorption (Yubing Sun, Shubin Yang, Yue Chen, Congcong Ding, Wencai Cheng, Xiangke Wang, Environ.Sci.Technol.2015,49,4255-4262), sewage it is net Change (Yi Han, Zhen Xu, and Chao Gao, Adv.Funct.Mater.2013,23,3693), ultracapacitor (Li, Meng;Tang, Zhe, Leng, Mei, et al.Adv.Funct.Mater.2014,24,7495-7502), fuel cell catalyst Agent (Jia, Lingpu, Sun, Xiao, Jiang, Yimin, et al.Adv.Funct.Mater.2015,25,1814-1820) etc. Multiple fields receive extensive research.How to prepare smooth two dimensional oxidation graphene film is asking for the continuous exploration of present people Topic.The method of preparation graphene oxide membrane also emerges in an endless stream and has LB methods (Laura J.Cote, Franklin Kim, and Jiaxing Huang.J.AM.Chem.Soc.2009,131,1043-1049), spin-coating method (Kymakis, Emmanuel; Savva, Kyriak, Stylianakis, Minas M, et al.Adv.Funct.Mater.2013,23,2742-2749), spray Coating (Parviz, Dorsa, Metzler, ShaneD., Das, Sriya, et al.small2015,11, No.22,2661- 2668) etc..Vacuum filtration is easy to operate due to its, and obtained film enjoys people compared with other liquid membrane formation process uniform grounds the most Pay close attention to.But the greatest problem that suction method faces is how to peel off graphene oxide membrane from substrate.If oxidation stone Black alkene film is too thin, then complete film cannot be peeled off from substrate;And if film is sufficiently thick, is completely dried graphene oxide and is also required to Plenty of time.Substrate is dissolved with corrosive liquids such as acetone in some experiments, and so obtained film pattern cannot keep smooth. So the advantage in order to utilize suction filtration graphene oxide membrane completely, it is possible to which further reduction obtains smooth graphene film, Allow for finding a kind of method of quick stripping graphene oxide membrane, further functionalization is realized so as to be transferred to various substrates Operation.
The content of the invention
Technical problem:The present invention provides a kind of quick stripping graphene oxide suction filtration film and the method for being transferred to substrate, can Peel off and shift to realize by the complete graphene oxide membrane rapid dehydration drying of firm suction filtration and from substrate.
Technical scheme:A kind of quick stripping graphene oxide suction filtration film of the present invention and the method for being transferred to substrate, including with Lower step:
Add graphene oxide into first in water, ultrasonic disperse forms graphene oxide aqueous dispersions, then puts substrate In on the core of bottle,suction, Suction filtration device is put up, the graphene oxide dispersion that will then prepare pours into Suction filtration device, start to take out Filter;Then the substrate that the good graphene oxide membrane of suction filtration will be adhered to takes out, and is put in organic solvent so that graphene oxide membrane is fast Fast drainage and formation, and split away off from substrate;By smooth substrate (such as silicon chip, glass, sheet metal etc.) directly organic molten Graphene oxide membrane in agent with floating is contacted, it is possible to so that graphene oxide film transfer is attached on substrate.
Wherein:
Described organic solvent is methyl alcohol, ethanol, acetone, tetrahydrofuran, DMF, DMA, DMSO, HMPA, fourth sulfone, dioxy six Ring, hydracrylic acid, ethamine, ethylenediamine, ethylene glycol, glycerine, ethylene glycol list first/second/propyl ether, diethylene glycol dimethyl ether or 1,3- dioxy One kind in heterocycle pentane.
Graphene oxide content in the graphene oxide aqueous dispersions is 0.1ug/mi~100mg/ml.
Described substrate is the material not reacted with described organic solvent.
The material of described substrate is polycarbonate membrane, pellumina or polyvinylidene fluoride film.
The substrate of transfer is PET, PP, silicon chip, glass, polytetrafluoroethylene (PTFE), PDMS or metal.
Graphene oxide membrane is obtained if necessary to further reduction, the method that can be reduced by high temperature thermal reduction, hydrazine is obtained Arrive.
In the present invention, the substrate of transfer is silicon chip, and glass, polyethylene terephthalate film, polypropylene resin film gathers Vinyl chloride film, poly tetrafluoroethylene, polyurethane film, poly- carbonic acid resin film, propylene be fine-and butadiene-styrene is common Polymer film, polystyrene film, polyvinyl alcohol film or the smooth flexibility of sheet metal or plastic substrate.
The present invention is dissolved each other well using organic solution and water energy, by making film inner layer between hydrone quickly be lost in from And dry forming, and graphene oxide good dispersion and poor dispersion in organic solvent in water, therefore produce repulsion from lining Depart from bottom.Because the flatness of film is higher, the method that can be depended on by directly contact is by film transfer to same smooth lining On bottom.
Beneficial effect:The present invention compared with prior art, with advantages below:
In existing data, there is no a kind of method that can quickly peel off the graphene oxide membrane after suction filtration.Due to oxidation Graphene film is often very strong with substrate combination degree through excessive pressure suction filtration, it is not easy to peeled off from substrate.It is most of all to connect Substrate is used together, which greatly limits the use scope of graphene oxide membrane.Existing stripping means has (1) by increasing oxygen Peeled off after graphite alkene film thickness is to be dried.This method can only obtain the very thick graphene oxide membrane of thickness, and due to wanting Could be peeled off when film is completely dried, increase thickness and be certain to so that drying time increases;Or (2) use severe corrosive solution such as Substrate is dissolved and obtains simple graphene oxide membrane by acetone.Film obtained in this method has certain deformation fold, Can not fully demonstrate suction filtration film it is smooth the characteristics of, and more or less can also residual substrate vestige.And pass through the method for the present invention, Can be completely without drying time, the time greatly shortens for peeling off thick film, while can also stripping film, put down Whole graphene oxide membrane, shape keeps very intact.And the substrate for peeling off can be recycled, and be economized on resources.And due to flat Whole degree is high, can easily be attached on smooth substrate, contacts very good.
