Problems solved by technology

This kind of process is cumbersome, the batch production efficiency is not high, the error is large when stacking, and a lot of manpower and material resources are required.
Moreover, the commonly used substrates of flexible electrochromic films are flexible materials. Before the flexible electrochromic film is packaged, it is easy to scratch and deform during storage and transportation. At the same time, the flexible electrochromic film is also vulnerable to ultraviolet rays when exposed to air. , water, oxygen, etc.
As a result, the existing flexible electrochromic films are not easy to store, and the packaging is cumbersome, so they are not suitable for direct sales as products.

Embodiment 1

[0094] This embodiment provides an intermediate layer of a flexible electronic device, such as figure 1 As shown, it includes a flexible electronic device, a first adhesive film and a second adhesive film disposed on both sides of the flexible electronic device, and a first release film disposed outside the first adhesive film and disposed on the The second release film on the outside of the second adhesive film;

[0095] Among them, the flexible electronic device is a flexible electrochromic film.

[0096] It should be noted, figure 1 The structure of the flexible electronic device shown in only means that when it is a flexible electrochromic film, it has a multi-layer structure, and should not be understood as having only three layers.

[0097] This embodiment also provides a preparation process for the above-mentioned intermediate layer of the flexible electronic device, such as figure 2 shown, including the following steps:

[0098] (1) Unwind the flexible electrochro...

Embodiment 2

[0108] This embodiment provides an intermediate layer of a flexible electronic device, the structure of which is the same as that of Embodiment 1, and the preparation process is as follows Figure 4 shown, including the following steps:

[0109] (1) Unwinding the flexible electrochromic film roll material (thickness 0.1mm), corona treatment is carried out to the flexible electrochromic film to increase surface tension;

[0110] (2) Using two pairs of rubber rollers, the packaging film is continuously pasted on both sides of the flexible electrochromic film after step (1) by rolling method (the raw materials used are heavy-release film, pressure-sensitive adhesive film A three-layer composite film with a light release film, the light release film is rolled and removed before attachment, and the packaging film attached to the surface of the flexible electrochromic film is a composite film of a heavy release film and a pressure-sensitive adhesive film. Wherein the heavy-release ...

Embodiment 3

[0119] This embodiment provides an intermediate layer of a flexible electronic device, the structure of which is the same as that of Embodiment 1, and the preparation process is as follows Figure 6 shown, including the following steps:

[0120](1) Unwinding the flexible electrochromic film roll material (thickness 0.3mm), and performing plasma treatment on the flexible electrochromic film to increase the surface tension;

[0121] (2) Use a pair of rollers to continuously attach the packaging film to both sides of the flexible electrochromic film after step (1) by rolling (the raw materials used are heavy-release film, EVA hot-melt adhesive film) A three-layer composite film with a light release film, the light release film is rolled and removed before attachment, and the packaging film attached to the surface of the flexible electrochromic film is a composite film of a heavy release film and an EVA hot melt adhesive film , wherein the heavy release film is on the outermost s...

Abstract

The invention provides a flexible electronic device intermediate layer and a preparation process thereof. The flexible electronic device intermediate layer comprises a flexible electronic device, an adhesive film arranged on one side or two sides of the flexible electronic device, and a release film optionally arranged on the outer side of the adhesive film. The preparation process comprises the following steps: unreeling a flexible electronic device roll material; and then continuously attaching packaging films to one side or two sides of the flexible electronic device through a rolling method to obtain the intermediate layer of the flexible electronic device. The intermediate layer of the flexible electronic device can protect the flexible electronic device and prevent the flexible electronic device from being scratched or influenced by factors such as ultraviolet rays, water and oxygen in the storage, transportation and packaging processes. According to the preparation process provided by the invention, the flexible electronic device intermediate layer can be efficiently produced, and the production efficiency of downstream products is improved.

Description

technical field [0001] The invention belongs to the technical field of flexible electronic devices, and in particular relates to an intermediate layer of a flexible electronic device and a preparation process thereof. Background technique [0002] With the development of electronic information technology, flexible smart devices are increasingly becoming the mainstream of current smart devices, such as flexible solar cells, flexible thin film batteries, flexible thin film capacitors, flexible OLEDs, flexible electronic writing paper, flexible thin film sensors, flexible thermochromic Flexible electronic devices such as thin films, flexible photochromic films, and flexible electrochromic films. Taking flexible electrochromic films as an example, the market demand for them in smart devices is becoming stronger and stronger. Electrochromism refers to the phenomenon that the optical properties (reflectivity, transmittance, absorptivity, etc.) of materials undergo stable and reve...
