Single-Walled Carbon Nanotube (SWCNT) membranes, commonly known as buckypapers, are freestanding, paper-like films composed of interconnected SWCNT networks. These membranes are highly porous, lightweight, and flexible, offering exceptional electrical and thermal conductivity, mechanical robustness, high chemical stability, and outstanding resistance under both thermal and cryogenic conditions. Their distinctive nanostructure and multifunctionality enable a wide range of applications, including energy storage, EMI shielding, aerospace structures, thermal management, sensing, filtration, and fire protection.

APPLICATIONS
SWCNT membranes demonstrate significant potential across a broad range of advanced applications:
- Energy Storage: SWCNT membranes are highly promising candidates as high-performance electrodes and current collectors in batteries and supercapacitors, combining excellent conductivity and flexibility for lightweight, wearable energy storage. They are also attractive as catalyst supports in fuel cells, where their high surface area, conductivity, and corrosion resistance enhance platinum dispersion, catalytic activity, and durability in PEMFCs.
- Electromagnetic Interference (EMI) Shielding: SWCNT membranes exhibit strong electromagnetic interference (EMI) shielding capabilities by reflecting, absorbing, and dissipating electromagnetic waves. Their conductive, interconnected nanotube networks make them viable for protecting sensitive electronics across consumer, aerospace, wearable, and defense applications
- Aerospace and Structural Applications: As lightweight and conductive films, SWCNT membranes can be integrated into composite structures to enhance mechanical strength and electrical conductivity, making them suitable for lightweight aerospace components and effective in providing lightning strike protection in aircraft and spacecraft.
- Thermal Management: Due to their high thermal conductivity, SWCNT membranes can serve as effective heat spreaders or thermal interface materials, enhancing heat dissipation in electronic and power devices.
- Sensing: SWCNT membranes can serve as chemical and biosensors, combining excellent flexibility, high sensitivity, and tunable surface chemistry to enable rapid, real‑time monitoring in wearable electronics and environmental sensing systems.
- Filtration and Separation: Their highly porous nanostructure and large accessible surface area make SWCNT membranes well-suited for filtration and separation, particularly in industrial and environmental remediation applications.
- Fire Protection: SWCNT membranes can enhance the fire resistance of materials by acting as a thermally stable barrier.
