MXenes for Defense-Oriented Multifunctional Systems: From Synthesis and Property Regulation to Deployment Challenges

Area of Science:

• Materials Science
• Nanotechnology
• Defense Technology

Background:

• MXenes are 2D transition-metal carbides/nitrides with metallic conductivity, tunable surfaces, flexibility, and solution processability.
• They offer a unique combination of electromagnetic, mechanical, thermal, and sensing properties, unlike conventional materials.
• Existing reviews often focus on lab performance; this work adopts a deployment-oriented perspective for military applications.

Purpose of the Study:

• To provide a systematic, military-oriented evaluation of MXenes from a deployment perspective.
• To bridge the gap between laboratory achievements and practical defense applications.
• To present a comprehensive framework linking MXene synthesis, property regulation, and military deployment.

Main Methods:

• Summarized MXene formation chemistry and synthesis routes (e.g., HF etching, molten-salt, CVD).
• Discussed property regulation strategies: composition design, surface termination control, and heterostructure engineering.
• Analyzed performance envelopes for shielding, stealth, impact response, energy storage, and sensing.

Main Results:

• MXene properties can be tailored for specific defense functions through material design.
• A full-chain analytical framework from synthesis to deployment challenges was established.
• Key barriers to MXene translation include manufacturing inconsistency, termination heterogeneity, degradation, and limited validation.

Conclusions:

• MXenes hold significant promise for multifunctional defense systems.
• Addressing manufacturing and degradation challenges is crucial for deployable MXene technologies.
• Further research on application-level validation is needed to realize MXene's full potential in defense.
