Area of Science:

• Materials Science
• Nanotechnology
• Surface Chemistry

Background:

• Low infrared emissivity materials are crucial for thermal management, security, and counter-surveillance.
• Metals are commonly used but have limitations like density, corrosion, and processing difficulties.
• Intrinsically low-emissivity nonmetallic materials are highly sought after.

Purpose of the Study:

• To review recent advances in MXene-based low-infrared-emissivity materials.
• To focus on the phenomena, mechanisms, and applications of these materials.
• To outline future research directions for MXene applications in infrared radiation thermal manipulation.

Main Methods:

• Systematic review of recent scientific literature on MXene-based low-emissivity materials.
• Analysis of underlying physical phenomena and operational mechanisms.
• Examination of diverse application landscapes.

Main Results:

• MXenes exhibit low intrinsic infrared emissivity, comparable to metals.
• Their solubility and tunable surface chemistry allow for easier, cost-effective processing.
• MXene systems show significant promise in adaptive thermal camouflage, infrared stealth, and thermal energy conversion.

Conclusions:

• MXenes present a compelling alternative to traditional metallic low-emissivity materials.
• Their unique properties enable advanced applications in thermal manipulation and infrared stealth.
• Further research is needed to address existing challenges and expand their use in infrared radiation control.
