Ele ctrostatic Forces effects on aggregation behavior of CTA B surfacta nt around carbon nanotubes

Single -walled carbon nanotu bes (SWCNTs) can be dispersed as individuals in water using surfactants. By co ntrolling the intermolecular and su rface forces of surfact ant in water, it is possib le to engineer the resultant VdW attraction bet ween SWNT s [۱]. On the other han d, one technique has been improved by Arnold et al. [۲], who, using bile salts such as sodium c holate in addition to surfactants, dem onstrated t hat it is possible to separate SWCN Ts on the basis of their diameter and electronic structure. However, i t is still not clear how surfactants self-assemble on SW CNTs in the presence o f salt. A d etailed understanding of the structu re of surfactant aggrega tes adsorbe d on SWCNTs in the pr esence of sal t is the goal of this wor k.
