Abstract：
The colorless and transparent polyimide films were prepared using 2 - bis ( trifluoromethyl ) diaminobiphenyl and cyclobutane tetracarboxylic dianhydride as raw materials, and ionic liquid 1 - ethyl - 3 - methylimidazolium bis ( trifluoromethyl ) sulfonimide salt was added. The embedded silver nanowire / polyimide composite conductive films were prepared using the simple and rapid spray and coating method, which had excellent transparency, low thin layer resistance, high thermal stability, bending resistance, and rapid electrothermal responsiveness. The composite films can be used as the electric heaters with high heating temperature at low voltage, demonstrating the application in display and heating human joints, and has broad application potential in scenarios such as wearable electronic devices.
