Description

Technical Field

[0001] This invention relates to the field of conductive film preparation, and particularly to a high-efficiency carbon fiber conductive film preparation device and its preparation method. Background Technology

[0002] A conductive film is a thin film with electrical conductivity. During transport, charged carriers in a conductive film are scattered by the surface and interface. When the thickness of the film is comparable to the free path of electrons, the influence of the surface and interface becomes significant. This phenomenon is called the size effect of the film, which is equivalent to a reduction in the free path of charge carriers. Therefore, compared with a bulk material of the same material, the conductivity of the film is smaller.

[0003] Existing conductive films have low strength, and their preparation process has a low degree of automation, which cannot guarantee the accuracy of the final product. Furthermore, the thickness and coating of the conductive film cannot be guaranteed to be consistent and uniform, resulting in inconsistent quality of the final product.

At this time, the winding roller (4) and the take-up roller (26) can be driven to rotate simultaneously until all the prepreg yarn is processed. The processed prepreg yarn is taken out from the outer wall of the take-up roller (26) and placed in the inner cavity of the oven (32) for curing treatment, thereby completing the film making process. S6: Place the membrane on the outer wall of the cutting seat (34), cut it according to the required size, observe the size of the membrane with the set scale (35), press the cutter (37) to cut the membrane, and after cutting, the spring (40) will drive the cutter (37) to reset, so as to facilitate subsequent cutting work.
