Abstract
MXene/chitosan (MX/CS) composites have recently garnered significant attention due to their unique properties. This synergistic integration has opened new opportunities for various industrial applications. This review provides a comprehensive analysis of recent advancements in the use of MX/CS composites across multiple sectors, including electromagnetic interference (EMI) shielding, electrochemical sensing, water treatment, fire-retardant materials, environmental remediation, and energy storage devices such as supercapacitors and batteries. Each application has its own requirements and standards for the chosen building materials. Fortunately, all the divergent requirements can be achieved in MXene (MX) and chitosan (CS) by relatively moderate treatment. The discussion highlights how the unique interactions between MX nanosheets and CS matrices enhance performance characteristics. Despite these advantages, several critical challenges remain, including long-term stability, material scalability, and cost-effective manufacturing processes. This review summarizes recent advancements by identifying key research gaps and aims to guide further innovation in the fields. The potential of MX/CS composites to contribute to sustainable and high-performance industrial solutions is undeniable, provided that existing challenges are met with innovative approaches.
