Laser-induced porous graphene from papers for microsupercapacitors |
| 초록 |
Recently, a one-step laser photothermal method to generate 3-dimensionally (3D) porous graphene from commercial aromatic polymer films has been demonstrated. Even though the method has allowed for a scalable production of 3D porous graphene, the use of the polymer precursors requires thermal and chemical process to synthesize. In this study, easily approachable papers are used as precursor materials to obtain 3D porous graphene through laser photothermal method. We first aromatize the paper precursors through the multiple laser irradiation, generate porous graphene by the laser photothermal method and fabricate microscale electrodes for microsupercapacitors. Our scalable, cost-effective and environmental friendly method to produce porous graphene from the papers holds promise to convert papers into valuable energy storage and wearable electronic materials. |
