| Outline of Final Research Achievements |
In this study, the redox chemistry of carbon nanotube (CNTs) was examined in the presence of surfactants. Redox reactions of the SWCNTs were observed in the present of sodium dodecyl sulfate, which was associated with the adsorption of CNTs onto polysaccharide gels. Molecular dynamics simulations were performed for investigating the assembly of the surfactant molecules around a CNT. The positively charged SWCNT as a model of the oxidized SWCNT showed an increase in the number of the surfactant molecules around the SWCNT. This result is consistent with the experimental phenomena in which more oxidized SWCNTs, i.e., narrower-band gap SWCNTs, have less affinity for polysaccharide.
