Description
Technical Field
The invention relates to the technical field of nano composite material preparation, in particular to a method for preparing a copper nanowire/graphene composite with an ultrahigh length-diameter ratio.
Background
The one-dimensional metal nano material has a special quantum size effect and has wide application value in the fields of optics, electrics, flexible wearable equipment devices and the like. The copper nanowire has the advantages of excellent electrical conductivity and thermal conductivity, abundant raw materials and low cost, and thus becomes one of the most promising one-dimensional metal materials. However, the low-cost synthesis of the copper nanowire with high aspect ratio and the easy oxidation of the copper nanowire still remain problems to be solved.
In patent CN201710224439.6, a method of using vitamin C as a reducing agent and octadecylamine as a capping agent is invented to prepare a copper nanowire with a relatively high long diameter, but the copper nanowire prepared by the method is easy to aggregate and difficult to be applied subsequently. Patent CN201811166559.6 discloses a method for preparing copper nanowires by using molten metal aluminum as a liquid phase, and although the copper nanowires obtained by the method have good dispersibility, the length-diameter ratio is not high, and the reaction conditions are harsh, so that the large-scale production and application are difficult. The graphene has excellent electric conductivity and heat conductivity, and has wide application fields. Research on the preparation of the composite material with excellent performance by compounding the graphene and the copper nanowire attracts wide attention of researchers, and Kholmanov et al prepares the electrode with the performance superior to that of the electrode made of the pure copper nanowire by compounding the graphene subjected to oxidation reduction and the copper nanowire. Although the stability and a certain degree of conductivity of the copper nanometer are improved, the application of the composite still has great limitation because the conductivity of the graphene after oxidation and reduction is poor. The surface of the copper nanowire is coated with graphene by using a vapor deposition method, such as Chenshihong, and the like, and the heat conduction and the electric conductivity of the coated copper nanowire are proved to be far superior to those of the uncoated copper nanowire. However, the method has harsh reaction conditions, requires a high temperature (650 ℃), has high requirements on equipment and high energy consumption, and therefore, the method limits large-scale application.
Disclosure of Invention
The present invention is directed to overcoming the above-mentioned drawbacks of the prior art and providing a method for preparing an ultra-high aspect ratio copper nanowire/graphene composite having excellent conductivity and stability.
The purpose of the invention can be realized by the following technical scheme:
a method of preparing an ultra-high aspect ratio copper nanowire/graphene composite, comprising:
reacting graphene with an alkali solution to obtain graphene containing a hydroxyl functional group;
adding copper chloride into oleylamine, and stirring at room temperature for a certain time to obtain a precursor solution;
mixing graphene containing hydroxyl functional groups with a precursor solution, heating for reaction, and separating after the reaction is finished to obtain the copper nanowire/graphene composite with the ultrahigh length-diameter ratio.
Further, the alkali solution includes strong alkali such as potassium hydroxide solution, sodium hydroxide or sodium ethoxide.
Further, the alkali solution is a potassium hydroxide solution.
Further, the concentration of the alkali solution is 1-5 mol/L.
Further, the mass ratio of the graphene to the alkali is 1:5-1: 20.
Further, the reaction temperature of the graphene is controlled to be 150-.
Further, the mass ratio of the copper chloride to the oleylamine is 1: 250-1:500.
Further, the copper chloride is stirred and reacted in oleylamine for 10-60min, preferably 30 min.
Furthermore, the mass ratio of the graphene containing the hydroxyl functional group to the copper chloride in the precursor solution is 1:2-2: 1.
Furthermore, the graphene containing hydroxyl functional groups and the precursor solution are mixed and heated for reaction at the temperature of 160-200 ℃ for 1-8h, and compared with the prior art which needs 650 ℃, the reaction temperature can be greatly reduced.
Furthermore, the temperature for mixing and heating the graphene containing the hydroxyl functional group and the precursor solution is preferably 170-180 ℃, and the time is 2-4 h.
Compared with the prior art, the composite of the copper nanowire and the graphene, which has the length of 160 mu m and the length-diameter ratio of up to 4000, can be prepared in situ. The copper nanowire and the graphene are closely combined through a chemical bond, so that the copper nanowire has excellent stability and conductivity. According to the invention, a large number of active sites exist on the edge and the surface of the graphene treated by the Plasma, and after the graphene is treated in a strong alkaline solution environment, the generated hydroxyl active sites can reduce copper ions, so that copper atoms are crystallized and grown on the graphene to form good combination, and the graphene and the copper nanowires are uniformly mixed, so that the reaction temperature can be greatly reduced. In addition, the growth of copper nanowires is affected by many factors, such as temperature, concentration, etc., different reaction conditions, and different growth environments of copper nuclei, and thus, different final results are obtained. The sheet resistance of the thin film electrode prepared by the copper nanowire/graphene composite with the ultrahigh length-diameter ratio prepared by adopting the specific process parameters is less than 0.026 omega/sq, and the sheet resistance of the thin film electrode is not changed after the thin film electrode is placed at room temperature for 30 days. The method is simple and feasible, and can realize large-scale preparation.
