Vertically aligned carbon nanotubes (VACNT) membrane parameters used to calculate the permeability and enhancement factor
| VACNTs density (tubes cm−2) | CNT diameter (nm) | Dynamic viscosity µ (Pa S) at 20 °C | Pressure difference Δp (torr) | Membrane thickness (µm) |
|---|---|---|---|---|
| 5 × 109–1 × 1011 | 8 | 1.002 × 10−3 | 140 | 25 |
