摘要：

Joule heaters based on flexible thin films have attracted a significant amount of attention in both academia and the industry. However, it has been highly challenging to fabricate such heaters. In this study, a one-step laser induction method was proposed to prepare fluorine-doped laser-induced graphene (F-LIG) with stable and superhydrophobic properties by confining a 355 nm ultraviolet laser at the interface between the fluorinated ethylene propylene (FEP) film and polyimide (PI) film. The superhydrophobic properties of the F-LIG composite films could be attributed to the doping of fluorine elements and the laser-processed microstructures, which could be tuned by laser processing parameters. Based on the processed F-LIG films, Joule deicing heaters were developed and their deicing efficiencies are 7 times higher than that of the undoped LIG-based deicing heater. The method will provide new means and ideas to develop LIG-based flexible devices.
