1. A method for preparing a conductive film, comprising:
obtaining a conductive paste, the conductive paste comprising a thermoplastic polyurethane, conductive particles, and an organic solvent, the conductive particles and the thermoplastic polyurethane being mixed in the organic solvent at a weight ratio of the conductive particles relative to the thermoplastic polyurethane ranging from 3:7 to 95:5, and the thermoplastic polyurethane being dispersed in the form of particles among the conductive particles;
adjusting a viscosity of the conductive paste to obtain a preset viscosity according to requirements of an application scenario;
applying the obtained conductive paste on a substrate;
drying the conductive paste on the substrate to obtain a conductive film; and
removing a portion of the conductive film from the substrate by using N-methylpyrrolidone according to a predefined pattern.
