preparation example Construction

[0065] According to the second aspect of the present invention, the present invention provides a kind of preparation method of polymer-graphite composite membrane, comprises the steps:

[0066] (a) subjecting the polymer film to plasma treatment;

[0067] (b) Graphite film was sputtered on the plasma-treated polymer film.

[0068] In the preparation method of the polymer-graphite composite film provided by the present invention, the molecular structure of the polymer film is enlarged by first carrying out plasma treatment on the polymer film, and the surface adhesion of the polymer film surface is enhanced, and then sputtering is used to make the polymer film The graphite film is firmly attached to the surface of the polymer film to obtain a polymer-graphite composite film, which makes the polymer-graphite film not only have excellent corrosion resistance and high temperature resistance, but also have lightning protection and anti-glare functions, and also have insulation The...

Embodiment 1

[0138] The present embodiment provides a kind of polyester-graphite composite film, and it comprises polyester film, is compounded with graphite film on polyester film, and its preparation method comprises the following steps:

[0139] (a) Preparation of graphite film-copper composite material

[0140] (a1) Carbonization, graphitization and calendering of the polyimide film were performed sequentially to prepare graphite film

[0141] The carbonization treatment includes the following steps: the first stage temperature is raised from room temperature to 300°C, and the heating time is 40 minutes; the second stage temperature is raised from 300°C to 480°C, the heating time is 45 minutes, and the temperature is raised to 480°C and then heat-insulated for 30 minutes ;The temperature in the third stage is raised from 480°C to 600°C, and the heating time is 420min; the temperature in the fourth stage is raised from 600°C to 700°C, and the heating time is 240min; 200min; the sixth s...

Embodiment 2

[0149] This embodiment provides a polyester-graphite composite film, which includes a polyester film, and the polyester film is composited with a graphite film. The difference between its preparation method and Example 1 is that the graphite film-copper composite material is as follows Prepared by steps: brush graphene slurry on copper foil, dry to obtain graphite film-copper composite material; other steps are the same as in Example 1, and will not be repeated here.

Abstract

The invention provides a polymer-graphite composite membrane, a preparation method and an application thereof and relates to the technical field of the composite membrane. The polymer-graphite composite membrane comprises a polymer membrane; a graphite membrane is compounded on the surface of the polymer membrane; the technical problem that the present polymer membrane cannot be applied to anti-corrosion and high temperature resisting products because of poor corrosion and high temperature resistance thereof can be relieved. The graphite membrane is compounded on the polymer membrane and the polymer membrane and the graphite membrane have a synergic effect, so that the polymer-graphite composite membrane provided by the invention has excellent anti-corrosion property and high temperature resistance, has lightning protecting and anti-dazzling functions, has a heat-insulating function and can be applied to more fields.

Description

technical field [0001] The invention relates to the technical field of composite membranes, in particular to a polymer-graphite composite membrane and its preparation method and application. Background technique [0002] Polymer films have excellent physical and chemical properties and recyclability, and are widely used in food, medicine, chemical and electronics industries, but the existing polymer films have poor corrosion resistance and high temperature resistance, which makes them unable to be used for In corrosion products and high temperature resistant products. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] One of the objectives of the present invention is to provide a polymer-graphite composite film to alleviate the technical problem that the existing polymer film has poor corrosion resistance and high temperature resistance, which makes it unable to be used for corrosion-resistant and high-temperature-resistant pro...
