Simple fabrication of laser-induced graphene functionalized with a copper-based metal–organic framework and its application in solid-state supercapacitors

Abstract

Flexible thin-film electronics based on functionalized laser-induced graphene (LIG) hold great promise for a diverse range of applications, including biosensors and energy storage devices. In this study, we present a...

Enhanced Performance of Laser-Induced Graphene Supercapacitors via Integration with Candle-Soot Nanoparticles

“…While polyimide sheets have been traditionally used as the precursor substrate, many other polymeric substrates have also been explored. − Due to its inexpensive and straightforward synthesis approach, yet highly conductive and high surface-area nature, LIG has gained popularity as an efficient electrode material for several electronic applications, with flexible supercapacitors being a prominent focus. − However, the capacitance achieved from pristine LIG materials is comparatively lower. To enhance the capacitance of LIG materials, they are often modified either by doping with electroactive atoms (such as nitrogen, sulfur, and phosphorus) − or coating with electroactive materials (for example, carbonaceous material, metal oxides, − metal phosphate, metal–organic frameworks, , and MXenes. , Such modification processes often involve complicated steps, leading to increased fabrication costs and complexity, deviating from the inherent simplicity and cost-effectiveness of the LIG process.…”
