preparation example Construction

[0050] A kind of preparation method of single-sided transfer type graphene membrane, described graphene membrane comprises following preparation method by:

[0051] Step 101: The glue sprayer 501 sprays the glue solution 1 on the base film 2 to form a glue film;

[0052] Step 102: Squeegee 502 to smooth the adhesive film after glue spraying to ensure that the thickness of the sprayed glue is uniform;

[0053] Step 103: the smooth film guide roller 503 rolls the film to make the film compact, and the rough rolling roller 502 rolls the film to make the film rough;

[0054] Step 104: Adding graphene powder and glue solution 2 to the transfer press roller group 8 to make the adhesive film become an adhesive graphene surface by means of transfer printing;

[0055] Step 105: Steps 1 to 4 are performed in sequence, and steps 1 to 4 are repeated two or more times;

[0056] Step 106: hot pressing roller 505 rolls the processed base film 2;

[0057] Step 107: The base film 2 processe...

specific Embodiment

[0064] In actual use, the base film 2 is sent out through the film outlet 6, the glue sprayer 501 sprays the glue solution 1 on the base film 2 to make it into a film, and the smoothing scraper 502 smoothes the sprayed film Ensure that the thickness of the sprayed glue is uniform, the smooth film guide roller 503 rolls the film to make the film compact, the rough rolling roller 502 rolls the film to make the film rough, and the transfer roller set 8 plus Graphene powder and glue solution 2 make the adhesive film become an adhesive graphene surface by transfer printing, repeat the above steps twice, continue to spray glue solution 1, continue to smooth, continue to roll, continue to transfer and roll, increase Adhesion effect, effectively prevent the glue and graphene powder from peeling off, and greatly enhance the electrical conductivity.

Abstract

A single-sided transfer type graphene film structure and a preparation method thereof are disclosed, comprising a graphene film body, the graphene film body comprises a base film, a graphene layer onone side of the base film, a sealant layer on one side of the graphene layer, the base film is manufactured into a graphene film by a film processing device, A membrane processing apparatus includes amembrane processing assembly and a hot-press roller and a cold-press roller, The film processing module comprises a glue spraying machine arranged in sequence, a leveling scraping, a smooth film guiding roller, a rough rolling roller and a transfer pressing roller group, wherein one end of the graphene film body is connected with a film outlet for transferring out a base film, and the other end is connected with a film winding shaft for rolling up the produced graphene film body. As the preparation method of the invention is simple, not only the adhesive force can be enhanced, the conductivegraphene powder can be stably maintained and adhered on the base film, but also the peeling off of the glue liquid and the graphene powder can be effectively prevented, and the conductivity can be greatly enhanced.

Description

technical field [0001] The invention relates to the field of conductive films, in particular to a single-side transfer printing graphene film structure and a preparation method thereof. Background technique [0002] A conductive film is a thin film having a conductive function. As a material for forming a conductive circuit on a substrate, conductive paints (sometimes called conductive pastes, conductive inks, etc.) containing conductive fillers such as silver powder and copper powder are known. for practical purposes. Generally, after the conductive paint is coated on the substrate by printing and other methods, the conductive film is made by sintering. [0003] Graphene is a new type of two-dimensional carbon material with a honeycomb structure composed of a single layer of carbon atoms. Graphene has excellent electrical conductivity, the electrical conductivity is 1.6 times that of copper; graphene has excellent transmittance to near-infrared, visible light and ultravio...
