Embodiment 1
[0032] A transparent conductive film, comprising: a transparent polyimide base film and a conductive layer attached to the surface of the transparent polyimide base film;
[0033] Among them, in the preparation process of the transparent polyimide-based film, 2 mmol of triethylamine, 0.1 mmol of dendritic polyamide-amine whose end group is an amino group, 0.92 mmol of 2-(3-aminophenyl)-5- Aminobenzimidazole was dissolved in 400ml of water, nitrogen was introduced to remove the air, and then 1mmol of 4,4'-(4,4'-isopropyldiphenoxy)bis(phthalic anhydride) was slowly added to control the temperature. The polyamic acid solution was coated on the cleaned and dried glass carrier surface, then kept at 90 °C for 1 h, and then kept at 180 °C and 210 °C for 1.2 h to obtain a transparent polyamic acid solution. Imide-based film;
[0034] The transparent polyimide base film was washed with acetone, ethanol and water in turn and dried, and then the surface of the transparent polyimide base...
