Key Functions
High-Temperature Resilience: Maintains structural stability in oxidizing/reducing atmospheres up to 800°C.
Chemical Resistance: Superior performance in alkaline, chloride, and reducing environments (e.g., molten salts, NH₃).
Electromagnetic Shielding: Inherent conductivity (10⁴–10⁵ S/m) enables EMI/RFI attenuation.
Catalytic Support: High surface area (0.5–2.5 m²/g) for catalyst substrate applications.
Customizable Permeability: Adjustable fiber layering achieves precise flow resistance (ΔP: 50–500 Pa @ 10 cm/s).
ApplicationS
Energy: Molten carbonate fuel cell electrodes, SOFC gas diffusion layers, battery current collectors.
Metallurgy: Molten metal filtration (Al, Zn alloys), sintering furnace exhaust purification.
Electronics: Conductive EMI shielding gaskets, plasma etching masks.
Chemical Processing: Caustic solution filtration, hydrogenation reactor catalyst carriers.
Nuclear: Radioactive particle capture in reactor coolant systems
