Abstract
Official abstract text for this publication.
The present invention relates to a method for the production of cross-linked carbon nanotube network which are selected from aerogels and xerogels with improved performance and characteristics thereof. The invention is also concerned with carbon nanotube networks which are selected from aerogels and xerogels produced by such processes and uses thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aerogel or xerogel having a covalently cross-linked carbon nanotube network comprising: carbon nanotubes, a solvent, and a linking molecule selected from group consisting of bis(diazonium) salts, multifunctional molecules suitable for 1,3-dipolar cycloadditions or Bingel condensations, electrophilic cross-linking molecules, and combinations thereof, wherein the solvent is in an amount that is less than 10% by weight. 2. The aerogel or xerogel according to claim 1 , wherein the solvent is selected from the group consisting of dimethyl formamide, benzene, dichloromethane, chlorobenzene, chloroform, toluene, xylene, dioxane, dimethylsulfoxide, thetrahydrofuran, amide solvents, and mixtures thereof. 3. The aerogel or xerogel according to claim 1 , wherein the carbon nanotubes are multi-walled carbon nanotubes. 4. The aerogel or xerogel according to claim 3 , wherein the multi-walled carbon nanotubes having 5 to 15 walls. 5. The aerogel or xerogel according to claim 1 , wherein an aspect ratio of the carbon nanotubes ranges from 100 to 10,000. 6. The aerogel or xerogel according to claim 1 , wherein an amount of impurities present in the carbon nanotube network is less than 5% by weight. 7. The aerogel or xerogel according to claim 1 , wherein the aerogel or xerogel has a density ranging from 15 to 300 mg/cm 3 . 8. A catalyst comprising the aerogel or xerogel according to claim 1 . 9. A catalyst support comprising the aerogel or xerogel according to claim 1 . 10. A non-reflective panel comprising the aerogel or xerogel according to claim 1 . 11. An electrode for an electrochemical device comprising the aerogel or xerogel according to claim 1 . 12. A filter material comprising the aerogel or xerogel according to claim 1 . 13. A gas adsorption medium comprising the aerogel or xerogel according to claim 1 . 14. A water purification medium comprising the aerogel or xerogel according to claim 1 . 15. An absorbent comprising the aerogel or xerogel according to claim 1 .
