Carbon nanotube reinforced PVAm/PVA blend FSC nanocomposite membrane for CO2/CH4 separation.

Highlights: [•] A blended PVAm/PVA membrane reinforced with carbon nanotubes was successfully prepared. [•] A selectivity of CO₂/CH₄ up to 45 was documented in the low pressure range (2–5bar). [•] A CO₂ permeance of up to 0.35m³ (STP)/m² hbar was documented in this range. [•] The addition of CNTs (1.0wt.%), provided good durability against compaction at elevated pressures.
