Study of relationship quantitativ eenthalpy absorption: n anotube-anionicsurfactant system as a case model

The undirectional growth of materials to form nanowires or nanotubes has attracted enormous intere st in recent years. CNT consist of graphitic s heets, which have been rolled up into a cylindrical shape[۱].These m aterials can produce as single-wall tube and multi-wall. Carbon nanot ube as first generation products of n anotechnol ogy in the ۱۹۹۱ has op ened new world for sc ientists.Function of carbon nano-tubes, opene d new horiz ons in the study of biol ogical prope rties. With inventing new methods for solubility of carbon nanotu be in water and biological environ ments prob lem of CNT solubility has solved. The carbon nanotube can be function byHydr ogenation [۲], Cycload ditions[۳], Polymer C omposites[ ۴], surfactants[۵] and… in two ways attracting non-cov alent and covalent . t hus they w ould be suitable carrie rs for transfer drugs m aterial into t he body tiss ues and cell s. In this m ethod, funct ion of nanot ubewith surfactant by attracting n on -covalen t and effects of structural paramete rs on enthalpy adsorption of surfa ctant on carbon nanotub e is studied.According to the results pol and hy d have the greatest effect on the ent halpy.
