Direct Laser Writing of Transparent Polyimide Film for Supercapacitor

Direct laser writing (DLW) is a convenient approach for fabricating graphene-based flexible electronic devices. In this paper, laser-induced graphene was successfully prepared on a thin and transparent polyimide film through the DLW process. Experiments have demonstrated that interdigital thin film...

In this paper, laser-induced graphene was successfully prepared on a thin and transparent polyimide film through the DLW process. Experiments have demonstrated that interdigital thin film capacitor prepared by the DLW method has a high specific capacitance of 8.11 mF/cm<sup>2</sup> and volume capacitance density of 3.16 F/cm<sup>3</sup> (0.05 mA/cm<sup>2</sup>) due to the doped fluoride in the laser-induced graphene. The capacitance is about 20 times larger than the super-capacitor based non-transparent polyimide film of the same thickness. Owing to its thin, flexible, higher electrochemical characteristics, the transparent polyimide film is promising for integrating and powering portable and wearable electronics.https://www.mdpi.com/2079-4991/10/12/2547direct laser writingsupercapacitortransparent polyimide film
