Electrochemical Switching of Laser-Induced Graphene/Polymer Composites for Tunable Electronics.

ABSTRACT: Laser reduction of graphene oxide (GO) is a promising approach for achieving flexible, robust, and electrically conductive graphene/polymer composites. Resulting composite materials show significant technological potential for energy storage, sensing, and bioelectronics. However, in the case of insulating polymers, the properties of electrodes show severely limited performance. To overcome these challenges, we report on a post-processing redox treatment that allows the tuning of the electrochemical properties of laser-induced rGO/polymer composite electrodes. We show that the polymer substrate plays a crucial role in the electrochemical modulation of the composites' properties, such as the electrode impedance, charge transfer resistance, and areal capacitance. The mechanism behind the reve
