Embodiment

[0059] A flexible and stretchable transparent copper-clad laminate sequentially includes a supporting substrate, a separation layer, a peeling layer, a base layer, an adhesive layer, a patterned metal layer and a patterned insulating layer. When in use, the release layer, base layer, adhesive layer, patterned metal layer, and patterned insulating layer are peeled off using the separation layer as a transition, and the patterned insulating layer is attached to the skin surface during use.

[0060] Such as figure 1 Shown, the preparation method of this transparent copper-clad laminate comprises the following steps:

[0061] S0, choose a hard sheet as the supporting substrate, and the supporting substrate can be used to provide a certain rigidity and hardness, which can be a glass sheet, a metal sheet or a plastic sheet, etc., and glass sheet is preferred in this embodiment;

[0062] S1, preparation of the separation layer: Spin-coat 10:1 PDMS on the support substrate (the ratio...

Abstract

The invention discloses a flexible stretchable transparent copper-clad plate. The flexible stretchable transparent copper-clad plate sequentially comprises a supporting base material, a separation layer which is prepared from at least one of PE, PVC and PDMS; a stripping layer which is made of at least one of PVA and PE; a base layer which is prepared from PDMS, wherein the ratio of a PDMS monomerto a curing agent is (1-30): 1; an adhesion layer which is made of PDMS, wherein the ratio of the PDMS monomer to the curing agent is 20-80: 1; a metal layer provided in a circuit board shape. When the flexible stretchable transparent copper-clad plate is used, the stripping layer, the base layer, the adhesion layer and the metal layer are stripped for use by taking the separation layer as a transition. With the arrangement of the stripping layer, certain viscosity exists between the stripping layer and the separation layer, and the separation of the stripping layer and the separation layer is facilitated. The viscosity of the adhesion layer is larger than that of the base layer, the base layer and the metal layer can be firmly adhered to the two sides of the adhesion layer, and meanwhile, the flexibility of the base layer is larger than that of the adhesion layer, and under the cooperation of the raw materials of all the layers, the copper-clad plate in the using state has good transparency and good flexible stretchable property.

Description

technical field [0001] The invention relates to the technical field of copper-clad laminates, more specifically, it relates to a flexible and stretchable transparent copper-clad laminate and a preparation method thereof. Background technique [0002] Flexible copper clad laminate (FCCL) has the characteristics of lightness, thinness and flexibility, and is the processing raw material for flexible circuit board (FPC). It contains at least two materials, one is an insulating substrate, such as polyimide (PI) film, liquid crystal polymer (LCP) film, etc.; the other is a metal conductor foil, mainly copper foil or silver foil gold foil Wait. [0003] The base material of the flexible copper clad laminate is generally polyimide material according to the material. By modifying the polyimide material in various ways, or adding specific metal components and performing high-temperature heating treatment, the polyimide material can be improved. Imide film properties, especially to i...
