Abstract
The synthesis of MXene-cobalt hybrid (MX-Co) is presented utilizing a molten salt approach, targeting the application in artificial muscle technology. Mxenes possess exceptional electronic conductivity and surface chemistry, making them ideal candidates for electrochemical applications. Cobalt, known for its ferromagnetic qualities, is a good match for MXenes and enhances artificial muscles' mechanical performance. By circumventing hazardous hydrofluoric (HF) acid, a facile and scalable synthesis process for MX-Co hybrids is demonstrated. Their structural and electrochemical characteristics are revealed through characterization using cutting-edge spectroscopic and microscopic techniques. When compared to typical PEDOT: PSS electrodes, electrochemical experiments show that MX-Co electrodes have higher electroactive performance, with enhanced bending deformation under various input conditions. MX-Co hybrids exhibit a specific capacitance of 77.34 F g-1, 1.6 times higher than PEDOT: PSS, and achieve a substantial enhancement of electrochemical bending displacement, up to 11.72 mm under a low input voltage of 1 V, showcasing their potential for soft actuator applications.
MXene-cobalt (MX-Co) hybrid electrodes are synthesized using an eco-friendly molten-salt method, capitalizing on MXenes' electronic conductivity and cobalt's mechanical properties. These electrodes exhibit superior electroactive performance, surpassing conventional PEDOT: PSS material, showcasing the potential of MX-Co in artificial muscle technology.image (c) 2024 WILEY-VCH GmbH
