Abstract: In this letter, we report the increase of permeation rates of some typical volatile organic compounds through entangled carbon nanotube networks by an electric current. The change in the permeation rate is reversible when the\ncurrent is turned off. The permeation rise is partly probably due to Joule effect and thus increased membrane temperature and vapor pressure in the vicinity of the inlet side of membrane. However, the effects of vapor polarity and electrostatic interaction of vapors and charged nanotubes seem to be also involved and contribute to the differentiation between alcohol and carbohydrate vapors permeation.
