Abstract

The invention discloses a green reduction preparation method of a self-supporting reduced graphene oxide thin film. The method comprises the following steps: pre-reacting a graphene oxide water solution with a reducing agent at normal temperature, and preparing a pre-reduced graphene oxide thin film through a suction filtering self-assembly method; and reacting the pre-reduced thin film with the reducing agent under a hydrothermal condition to obtain the self-supporting graphene oxide thin film. The reducing agent adopted by the method is non-toxic, environmentally friendly, naturally degradable and free from environmental pollution, and the preparation process is simple and easy to control.

Description

A kind of green reducing preparation method of self-supporting oxidation graphene film
Technical field
The present invention is specifically related to a kind of self-supporting oxidation graphene film preparation method, belongs to technical field of nano material.
Background technology
Graphene is a kind of bi-dimensional cellular shape crystalline network carbonaceous material by the tightly packed one-tenth of monolayer carbon atom.Because it has special nanostructure and the performance of excellence, the material based on Graphene shows huge application potential at numerous areas such as electronics, optics, magnetics, biomedicine, catalysis, sensor, energy storage.
Graphene film is one of focus of Graphene research, and graphene film obtains based on graphene oxide film usually.Because graphene oxide film oxy radical number is many and conduct electricity hardly, limit its application in electron device, recover its electroconductibility must reduce to graphene oxide film.
Graphene oxide film reduction is prepared graphene film and generally can be adopted two kinds of methods: (1) hydrazine steam reduction graphene oxide membrane, reheating annealing reduction; (2) there iing dispersion agent to deposit chemical reduction graphene oxide solution in case, obtaining graphene film by the graphene oxide solution of reduction, reheating annealing reduction.In the method for hydrazine steam reduction graphene oxide membrane, because the vapour permeability of grapheme material is poor, steam reduction can only be worked in uppermost surface, causes sheet resistance to reach capacity along with the thickness increase of film.Another kind method is chemical reduction graphene oxide in the solution, usually needs to use the poisonous or expensive reagent such as hydrazine or sodium borohydride, and causes environmental pollution.
Summary of the invention
The object of the invention is a kind of method adopting green reduction, first by graphene oxide water solution and reductive agent pre-reaction at normal temperatures, suction filtration self-assembly obtains prereduction graphene oxide film, then prereduction graphene oxide film and reductive agent is reacted obtained self-supporting graphene film under hydrothermal conditions.
A green reducing preparation method for self-supporting oxidation graphene film, comprises the steps:

(2) by the tetrafluoroethylene millipore filtration vacuum filtration of prereduction graphene oxide mixing solutions obtained for step (1) by 0.22 micron, aperture, peel off and remove tetrafluoroethylene millipore filtration, obtained prereduction graphene oxide film crude product, to be placed in 80 ~ 150 DEG C of vacuum drying ovens dry 16 ~ 24 hours, obtained prereduction graphene oxide film;
(3) described prereduction graphene oxide film is placed in water heating kettle, adding mass concentration is 2.5 ~ 20mg/mL reductive agent aqueous solution, hydro-thermal reaction is carried out 16 ~ 24 hours under 90 ~ 150 DEG C of conditions in water heating kettle, obtained oxidation graphene film crude product, the mass ratio of wherein said reductive agent and prereduction graphene oxide is 0.5: 1 ~ 4: 1;
(4) take out described oxidation graphene film crude product, after rinsed with deionized water, drying, obtain self-supporting oxidation graphene film;
Wherein said reductive agent refers to the one in mesna, xitix or sodium ascorbate.
Preparation method of the present invention, the reductive agent of employing is nontoxic, can natural degradation, and environment-friendly, non-environmental-pollution, preparation process is simple and easy to control.
