Abstract
Official abstract text for this publication.
The present disclosure relates to a method for making a carbon nanotube sponge. A carbon nanotube film structure comprising a plurality of carbon nanotubes and an oxidizing solution formed by an oxidizing agent and hydrogen peroxide is provided. The carbon nanotube film structure is soaked in the oxidizing solution to form a preform. Finally, the carbon nanotube sponge is obtained by freeze-drying the preform under vacuum condition. The present disclosure also relates to a carbon nanotube sponge obtained by above method.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for making a carbon nanotube sponge, the method comprising: providing a free standing carbon nanotube film structure comprising a plurality of carbon nanotubes combined by van der Waals force, and an oxidizing solution formed by an oxidizing agent and hydrogen peroxide; soaking the free standing carbon nanotube film structure in the oxidizing solution to form a preform; and freeze-drying the preform under vacuum condition.…
