Description
Technical field
The present invention relates to a kind of preparation method of the nano composite material based on the graphene oxide autocatalysis, is that the starting material single stage method prepares the graphene nano matrix material with graphene oxide and metal-salt, belongs to nano material, functional materials technical field of chemistry.
Background technology
Graphene is up to now, the thinnest in the world material-monatomic thickness of material.Not only have excellent electric property, light weight, thermal conductivity is good, and specific surface area is big, and Young's modulus and breaking tenacity also can compare favourably with carbon nanotube, but also have some particular performances, like quantum hall effect, quantum tunneling effect etc.Because the nanostructure of above uniqueness and excellent performance, Graphene can be applicable in the many advanced material and device, like thin-film material, energy storage material, liquid crystal material, mechanical resonator etc.; Graphene is a mono-layer graphite, and raw material is easy to get, so low price costs an arm and a leg unlike the carbon nanotube that kind, so Graphene is expected to replace carbon nanotube to become the high quality filler of polymer-based carbon carbon nano-composite material.
Preparation at present is based on the nano composite material of Graphene and few, mainly is because the neither hydrophilic also oleophylic not of Graphene, and reactive behavior is not high.Make it is carried out difficulty of modification ratio, thereby cause with other material compound also relatively more difficult.Now preparation graphene nano matrix material mainly is to let graphene oxide and other material compound earlier, again will graphene oxide wherein reduces to obtain the graphene nano matrix material; Perhaps compound with Graphene and other material of modification.
The graphene oxide that Liang etc. prepare the Hummers method is scattered in and carries out supersound process in the water, and under stirring action, adds Hydrazine Hydrate 80, processes the graphite oxide of partial reduction.In the graphite oxide dispersion liquid of partial reduction, add the acetone soln of epoxy resin/stiffening agent then, and carry out supersound process, under agitation stoichiometric number hour.Reaction is back to be descended drying and processes suitable shape at 60 ℃, then at 250 ℃ of logical N
2Situation under the 2h that anneals, unreduced graphite oxide is thoroughly reduced, thereby increases its electroconductibility.Obtain the matrix material of Graphene/epoxy resin at last, its electromagnetic shielding effect has reached commercial applications requirement (20 decibels) basically smaller or equal to 21 decibels.
Watcharomne etc. have prepared Graphene/SiCh nano composite material with sol-gel method.With graphite oxide/SiO
2Colloidal sol is applied on the borosilicate glass, places the container that is full of Hydrazine Hydrate 80 steam to reduce in dried sample then, finally obtains Graphene/SiO
2Nano composite material.And increased 400 ℃ of its electric conductivitys of the sample of handling, this is because the fixed density in matrix of Graphene that causes of sample increases, and has reduced the spacing between Graphene, has increased the path of conduction, thereby has increased electric conductivity.Graphite oxide/SiO
2The transsmissivity of nano composite material is fine, through the reduction after because " greying " thus cause transsmissivity to reduce.Employing solution mixing methods such as Chao have prepared the nano composite material of Pt, Pd, Au and Graphene.The precursor salts solution that is about to precious metal (Pt, Pd, Au) and terepthaloyl moietie join in the graphite oxide aqueous solution after ultrasonic, react 6h down at 100 ℃, have finally obtained Graphene/metal particle nano matrix material.They find that terepthaloyl moietie can be used as the reductive agent of graphite oxide, and terepthaloyl moietie is nontoxic, and are all harmless to human and environment, thereby have overcome the toxicity of graphite oxide reductive agent Hydrazine Hydrate 80 commonly used.Li etc. have also prepared Graphene/Pt nano composite material, and find that its catalytic effect for methanol oxidation is better than Pt/ Cabot graphitized carbon black.Photoactivation reduction methods such as Williams have obtained Graphene/TiO
2Nano composite material.Graphite oxide is added the TiO that obtains through the titanium isopropoxide hydrolysis
2In the ethanol colloid, and carry out supersound process, thereby obtain graphite oxide/TiO
2Nano dispersion fluid; Under the irradiation of UV-light, graphite oxide is reduced again, finally obtained Graphene/TiO
2Nano composite material.The Graphene that can observe in the matrix material through AFM is individual layer or bilayer.Graphite oxide/TiO without UV-irradiation
2Resistance be 233 kilohms, behind the UV-irradiation of 2h, the Graphene/TiO that obtains
2The resistance of nano composite material is 30.5 kilohms, and this approaches 1/8 of original resistance.
In sum, graphene composite material is because unique nanostructure and excellent performance are expected to become advanced special type function material such as one type of new electronic material, thin-film material, energy storage material, liquid crystal material, catalytic material.The graphene nano matrix material is the key areas that Graphene is used, although the nano composite material progress of Graphene is slow.Along with deepening continuously of research, the nano composite material of Graphene will get more and more, and its Application Areas and application prospect are with boundless.
