Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
As shown in fig. 1 to 4, the device using a conductive sheet as a graphene layer power supply electrode according to the present invention includes a substrate 1, a conductive sheet 2, a graphene layer 3, and gas holes 4, wherein the graphene layer 3 covers the substrate 1, the conductive sheet 2 is fixed on the substrate 1 through the graphene layer 3, and the conductive sheet 2 is provided with the gas holes 4. The air holes penetrate through the conducting strip 2, and the distance between adjacent air holes is preferably less than 7mm, and preferably 1mm to 4 mm.
As shown in fig. 3, the present invention may further include a wire 5 and a bonding pad 6, wherein the wire 5 is connected to the conductive sheet 2 through the bonding pad 6.
As shown in fig. 4, the graphene layer 3 of the present invention may be circular or have other shapes, and the corresponding conductive sheet 2 may be provided in two semicircular shapes. The method disclosed by the invention can be used for conveniently finishing the processing production similar to a special shape.
The substrate 1 of the device can be made of materials such as high borosilicate, microcrystalline glass, mica sheets and ceramics, and the conducting strip 2 can be a metal sheet such as a metal silver sheet and a metal copper sheet, and can also be a flexible graphene sheet and a graphene electrode sheet.
The substrate 1 in this step may be borosilicate, glass ceramic, mica sheet, ceramic, or the like.
The method for using the conductive sheet as the graphene layer power supply electrode comprises the following steps,
step one, arranging a plurality of air guide holes on the conducting sheet, wherein the air guide holes can be determined according to actual conditions, for example, the diameter of each air guide hole can be 0.5mm to 3mm, preferably 1mm to 2 mm. The air guide holes must penetrate through the conducting strips and cannot be blind holes, and in the subsequent processing process of the blind holes, gas evaporated by graphene slurry cannot be discharged, so that bubbles or connection loosening at the bottoms of the conducting strips can be caused, and the purpose of the invention cannot be realized. In this step, the distance between adjacent air holes is preferably less than 7mm, and preferably 1mm to 4mm, so that good conductive connection performance can be ensured, and the air holes can be conveniently processed.
As a further scheme of the invention, a conducting wire is welded on the conducting sheet, and then the air guide hole is processed. Or the conducting strip is firstly processed with the air guide hole and then welded with the conducting wire, and after welding, the distance between the conducting wires at the welding position is confirmed to be smaller, so that the method is suitable for the subsequent processing steps. Therefore, after the conductive sheet is adhered to the graphene layer, the conductive sheet does not need to be processed again, and is particularly suitable for materials which are inconvenient to weld like transparent glass. And because welding in advance, can not appear in the welding process to graphite alkene layer secondary heating, can not cause the influence to graphite alkene layer.
And step two, adhering the graphene slurry to the base material, adhering the conducting strip to the base material through the graphene slurry, and drying the graphene slurry. The graphene slurry can be adhered to the substrate in a screen printing mode, then the conducting strip is directly attached to the graphene slurry, the conducting strip can be fixed to the substrate due to the fact that the graphene slurry is sticky, and after drying, the conducting strip is stably fixed to the substrate. And forming the graphene layer by the dried graphene slurry. The drying process comprises the following steps: and slowly heating the substrate to the high temperature from the normal temperature for drying, ensuring that the substrate is not cracked, ensuring that the graphene slurry is not foamed, stabilizing the substrate at the drying temperature, and cooling the substrate to the normal temperature from the high temperature after drying, and also ensuring that the substrate 1 is not cracked. The drying temperature is 300 ° to 800 °, preferably 540 ° to 560 °, preferably 550 °, for 20 minutes to 50 minutes.
