Production of stable aqueous dispersions of carbon nanotubes

   
   

Methods of producing stable dispersions of single-walled carbon nanotube structures in solutions are achieved utilizing dispersal agents. The dispersal agents are effective in substantially solubilizing and dispersing single-walled carbon nanotube structures in aqueous solutions by coating the structures and increasing the surface interaction between the structures and water. Exemplary agents suitable for dispersing nanotube structures in aqueous solutions include synthetic and natural detergents having high surfactant properties, deoxycholates, cyclodextrins, chaotropic salts and ion pairing agents. The dispersed nanotube structures may further be deposited on a suitable surface in isolated and individualized form to facilitate easy characterization and further processing of the structures.

Os métodos de produzir dispersões estáveis de estruturas único-single-walled do nanotube do carbono nas soluções são conseguidos que utilizam agentes do dispersal. Os agentes do dispersal são eficazes substancialmente em solubilizing e em dispersar estruturas único-single-walled do nanotube do carbono em soluções aqueous revestindo as estruturas e aumentando a interação de superfície entre as estruturas e a água. Os agentes exemplary apropriados para estruturas dispersando-se do nanotube em soluções aqueous incluem os detergentes sintéticos e naturais que têm as propriedades elevadas do surfactant, os deoxycholates, os cyclodextrins, sais chaotropic e íon emparelhando agentes. As estruturas dispersadas do nanotube podem mais mais ser depositadas em uma superfície apropriada no formulário isolado e individualized para facilitar a caracterização fácil e processar mais adicional das estruturas.
