The invention provides the preparation method of the TPU conductive film, through a mode of preparing a base film and a coating film, the coating treatment is carried out in combination with the prepared conductive liquid, then the coating film is compounded on a surface through calendering, the whole adhesion stability can be ensured, the peeling can be avoided, the whole structure strength can be improved, the film is prepared from reasonably-matched materials, the process is simplified, the control flow is facilitated, in this way, the production processing convenience and the use stability can be substantially improved, and the promotion and the use are facilitated.

Description

technical field [0001] The invention relates to the technical field of conductive films, in particular to a preparation method of a TPU conductive film. Background technique [0002] Conductive polymer materials have achieved rapid development in the past few decades, and have been widely used in industries such as automobiles, printing, and electrical appliances. Conductive polymer materials are mainly divided into composite conductive polymer materials and structural conductive polymer materials. Forming, low cost and other advantages, among which TPU material film is the most widely used. [0003] However, the film material used in the existing TPU conductive film is relatively single, the structural performance of the film itself is poor, and the carrying capacity is weak, which is not conducive to stable use. Moreover, when conducting conductive material compounding, not only the process is complicated, which is not conducive to control, but also The composite force of...
