Silver nanowires (AgNWs) films are a promising alternative to indium tin

oxide (ITO) as transparent conductors, but their adhesion and thermal

stability are limited. We prepared a transparent conductive film by

bonding PEDOT:PSS with graphene and AgNWs on a hydrophilically treated

polyethylene terephthalate (PET) substrate. This improved the film’s

thermal stability and reduced resistivity due to enhanced adhesion. The

sheet resistance of the flexible AgNWs/GR/PEDOT:PSS composite film

decreased to about 20 Ω/sq at approximately 80 % transmittance, with

minimal changes after bending tests, indicating good adhesion to PET.

The composite film also demonstrated excellent stability under long-term

storage and high temperatures (up to 106 °C). Joule heating evaluations

revealed an average heating rate of 7.19 °C/s at low bias voltages

(6.0–12.0 V), highlighting its potential for flexible transparent

heaters in future electric heating devices.
