Biocompatible Parylene-C Laser-Induced Graphene Electrodes for Microsupercapacitor Applications.

ABSTRACT: Laser irradiation of polymeric materials has drawn great attention as a fast, simple, and cost-effective method for the formation of porous graphene films that can be subsequently fabricated into low-cost and flexible electronic and energy-storage devices. In this work, we report a systematic study of the formation of laser-induced graphene (LIG) with sheet resistances as low as 9.4 Ω/sq on parylene-C ultrathin membranes under a CO₂ infrared laser. Raman analysis proved the formation of the multilayered graphenic material, with I_D/I_G and I_2D/I_G peak ratios of 0.42 and 0.65, respectively. As a proof of concept, parylene-C LIG was used as the electrode material for the fabrication of ultrathin, solid-state mic
