preparation example Construction

[0023] On the other hand the present invention provides the preparation method of aforementioned a kind of graphene composite conductive fabric, comprises the following steps:

[0024] ① Mix graphene oxide or graphene with a solvent to obtain a graphene oxide or graphene dispersion;

[0025] ② uniformly spray the graphene oxide or graphene dispersion prepared in step ① on the surface of the polymer fabric through a high-pressure spray gun to obtain a graphene dispersed fabric;

[0026] ③ heat-treating the graphene dispersed fabric prepared in step ② to obtain a graphene composite conductive fabric.

[0027] It is worth mentioning that the method of spraying in step ② is that graphene or graphene oxide is evenly covered on the surface of polymer fabrics, and the amount of graphene or graphene oxide is less, less waste and less pollution. Graphene dispersion, in step ③, due to heating and drying, graphene oxide will be thermally reduced to graphene, that is to say, no matter it...

Abstract

The invention relates to the technical field of conductive fabrics and in particular to a graphene composite conductive fabric, comprising a polymer fabric, wherein the surface of the polymer fabric is uniformly sprayed with graphene; the mass ratio of the graphene to the polymer fabric is (0.00001~0.01):1; and the graphene has 1 to 8 sheet layers. The graphene composite conductive fabric is prepared by dissolving graphene oxide or graphene in a solvent to obtain a graphene oxide or graphene dispersion liquid and then performing spraying and drying. In the preparation method, in the process of heating and drying, great Van der Waals' force exist between the two-dimensional sheets of the graphene and between the two-dimensional sheets of the graphene and the polymer fabric so as to achieve great adhesive force. The method of the invention is simple, low in energy consumption, friendly to environment and free of pollution, can be used for large-scale commercial production, and improves the electrical conductivity and the durability of the conductive fabric by means of the good electrical conductivity, the high mechanical strength and the good adhesive ability of the graphene.

Description

technical field [0001] The invention relates to the technical field of conductive fabrics, in particular to a graphene composite conductive fabric and a preparation method thereof. Background technique [0002] Conductive fabrics endow traditional fabrics with conductive properties, which can be used in various industries, so that traditional fabrics can get rid of the problems caused by static electricity in many special applications. [0003] The preparation of conductive fabrics is still being explored. At present, the method of preparing conductive fabrics is antistatic agent impregnation method. Its advantages are low cost and simple process, but its disadvantages are low conductivity, poor durability and washing resistance; The method of mixing conductive fibers into the fabric has the advantages of good performance and high mechanical strength, but the disadvantage is that the process is complicated and the cost is high; there is a direct coating method, which has the...
