Poster summary

Laser processing of nanocarbon films emerges as fast, sustainable, and cost-effective method on a broader range of nanomaterials. This study describes the laser-induced production of reduced graphene oxide with carbon nanotube composites and their application as flexible electrodes. Electrodes containing CNTs exhibit 7.5-fold increase in conductivity compared to only rGO electrodes. Upon bending, the change in conductivity is lowered from 0.62 to 0.19. Furthermore, when used as electrodes in flexible supercapacitor devices, the composites with CNTs show 98.45 % retention in specific capacitance while maintaining structural integrity. In contrast, rGO electrodes without CNT addition deform upon bending and retain only 63.88 % of the relaxed specific capacitance.
