제목 Origin of Molecular Interaction between Carbon Nanotube and Surfactant
초록 The effects of surfactant structure on the solubilization of single wall carbon nanotubes (SWNTs) are investigated using atomistic molecular simulation. The solubilizing effects are evaluated in terms of binding energy of surfactant onto SWNT. The energy minimization calculations show that π-like stacking of ring moiety and longer alkyl chain length lead to the significant increase in the binding energy of surfactant molecules to SWNT. The results also show that it is energetically more favorable for most surfactants to lie on the tube surface parallel to the cylindrical axis than to bend around the nanotubes. In addition, we find that T-shaped surfactant consisting of hydrophobic rigid backbone and hydrophilic flexible side chain is more advantageous for solubilizing SWNT than flexible linear surfactants.
