| abstract |
The present invention is a method for producing a carbon aerogel from agglomerated carbon nanotubes, which comprises the following steps: (A) making an aqueous dispersion of carbon nanotubes in water in the presence of a dispersant; ) By expanding by the action of gas in the presence of a blowing agent to form bubbles from the aqueous nanotube dispersion of step (A), and (C) the bubbles obtained in step (B) It relates to a method comprising the steps of freezing and removing the water by sublimation. The present invention also relates to the carbon aerogel thus obtained, and further essentially relates to its use as a separation material or biomaterial. |
