In this work, MAXene/SiC-based conductive ink electrodes were successfully fabricated using a simple and low-cost direct writing method. MAXene nanomaterials were synthesized and combined with silicon carbide (SiC) nanoparticles to prepare conductive electrochemical ink. Chitosan solution was used as a binder to improve the adhesion stability of the electrode materials on the substrate surface. The obtained ink was manually written onto a PVC substrate to form electrochemical electrodes and dried at room temperature. The fabricated electrodes demonstrated good film formation and conductive properties, indicating the potential of MAXene/SiC composite materials for electrochemical applications. The proposed approach provides a facile strategy for the development of flexible and low-cost electrochemical platforms.
